Summary

Adds error_detail to the live ACTIVITY_LOGGED WebSocket broadcast so the canvas renders an actionable error reason (e.g. oauth_org_not_allowed) instead of the opaque dead-end phrase.

Root cause (#1420 / internal#212): error_detail was stored in the DB but never broadcast, so the canvas could only show "Agent error (Exception) — see workspace logs for details."

Server (Go)

  • logActivityExec in activity.go now includes error_detail in the broadcast payload when set (omitted when nil, matching the request_body/response_body pattern)
  • 2 new tests: TestLogActivity_Broadcast_IncludesErrorDetail, TestLogActivity_Broadcast_OmitsNilErrorDetail

Canvas (TypeScript)

  • useChatSocket: extracts error_detail from ACTIVITY_LOGGED payload; passes to onSendError with precedence: error_detail > summary > generic hint
  • Old dead-end phrase removed; generic fallback is now: "Agent error — please try again or check the agent's configuration."
  • 8 new tests covering error_detail/summary/generic/empty/wrong-workspace/ok-status cases

Test plan

  • go test ./... — all 37 packages pass
  • npm test — 3316 tests pass
  • npm run build — canvas compiles successfully

  set (omitted when nil, matching request_body/response_body pattern)
- New tests: broadcast includes error_detail / omits when nil

**Canvas (TypeScript)**

Canvas UI review (core-uiux):

useChatSocket.ts: Clean change — extracts error_detail from the WebSocket payload and prefers it over the generic fallback. The fallback hierarchy (error_detail > summary > generic) is the right priority. The generic fallback is still informative ("check the agent's configuration"), not opaque. No new UI elements.

UX improvement: Users will now see actionable errors like "403 Forbidden: oauth_org_not_allowed" instead of the dead-end "Agent error (Exception)".

No WCAG concerns — no new UI, no form inputs, no accessibility changes. Pure UX/text improvement to existing error path.

Targeting staging: correct for a two-phase promotion.

lgtm from canvas UX perspective.

PR #1472 Review — core-fe

Approve

Fullstack-engineer, staging-based. Addresses issue #1420: the canvas was showing opaque "Agent error (Exception) — see workspace logs for details." instead of the actionable error reason from the workspace agent (e.g. "403 Forbidden: oauth_org_not_allowed — Your organization has disabled Claude subscription access").

Canvas changes (small, focused):

  • useChatSocket.ts (+12 lines): extracts error_detail from ACTIVITY_LOGGED payload with a type guard (typeof p.error_detail === "string"), passes it as the error display message. Priority: error_detail > summary > generic fallback. The old dead-end message is removed.
  • New test file useChatSocket.errorDetail.test.ts (+204 lines): 8 test cases covering error_detail present, summary fallback, generic fallback, empty/error_detail absent, wrong workspace filtering.

TypeScript quality: Clean — no any, proper type guard, descriptive variable names, inline comment documenting the priority logic.

Note: Staging-based. Will be fully reviewed when it promotes to main. Canvas changes are minimal and low-risk — error display only.

[core-qa-agent] APPROVED — tests pass. e2e: N/A — both/workspace-server+canvas fix, e2e unavailable (no platform in container).

Tests run on PR branch:

  • Go activity tests: 2/2 PASS (TestLogActivity_Broadcast_IncludesErrorDetail, TestLogActivity_Broadcast_OmitsNilErrorDetail)
  • Full Go handler suite: 36/36 PASS (coverage 69.3%)
  • Canvas useChatSocket errorDetail tests: 8/8 PASS

Code quality: clean, targeted fix. activity.go adds error_detail to WS broadcast payload (nil-guard). useChatSocket.ts surfaces error_detail > summary > generic hint — replaces opaque "Agent error (Exception)" with actionable error reason (e.g. oauth_org_not_allowed). Both sides have regression tests. No regressions.

[core-security-agent] APPROVED — OWASP XSS/Injection clean. error_detail is extracted from platform-gated ACTIVITY_LOGGED payload (auth-gated handler); React renders via JSX expression with no innerHTML; workspaceId guard ensures scope isolation. Comprehensive test coverage on both TS (204-line) and Go (93-line) sides. No auth middleware, SQL, or exec concerns.

infra-sre review

APPROVE — clean two-sided fix for #1420.

Platform side (activity.go)

error_detail was already stored in the DB but never included in the live WebSocket broadcast — the canvas always received the opaque "Agent error (Exception)" fallback. The fix adds error_detail to the broadcast payload (capped at 4096 chars by the runtime's report_activity helper).

Two test cases: one asserts the field is included in the broadcast when non-nil, the other verifies it's absent when nil (matching the omission pattern of request_body/response_body).

Canvas side (useChatSocket.ts)

Priority chain: error_detail (most actionable, e.g. oauth_org_not_allowed) → summary (contextual) → generic hint (never the old "Agent error (Exception)" phrase). The generic hint is a UX improvement over the previous opaque phrase.

Workspace isolation is correct: cross-workspace events with error_detail do not trigger onSendError. status: ok with error_detail is also filtered — only error status surfaces the error.

Test coverage

  • Canvas: 7 cases including the cross-workspace guard, empty-string fallthrough, and no-op guard (when onSendError is undefined).
  • Go: 2 cases including nil omission.

One non-blocking note: the generic hint is slightly different from the old fallback ("please try again or check the agent's configuration" vs "see workspace logs for details"). The new wording is more actionable — good change.

No infra concerns. The error_detail cap at 4096 chars is set by the runtime, not enforced server-side here, but that's fine since 4096 chars covers essentially all real error messages.

Review: fix/issue-1420-actionable-errors

Approve. Clean fix that closes #1420 cleanly.

What's good

  • Go side (activity.go): error_detail was already stored in the DB and returned via GET /activity — this change adds it to the live WebSocket broadcast payload so the canvas gets it without polling. Simple addition to logActivityExec in the right place.
  • Canvas side (useChatSocket.ts): Uses error_detail as the primary display error, then falls back to summary, then to a generic hint. Avoids the opaque "Agent error (Exception)" message by surfacing actionable reasons (e.g. "403 Forbidden: oauth_org_not_allowed...").
  • Go test (TestLogActivity_Broadcast_IncludesErrorDetail): Covers the happy path with a real 403-style error detail string. TestLogActivity_Broadcast_OmitsNilErrorDetail guards against nil leaking as an empty string.
  • Canvas test (useChatSocket.errorDetail.test.ts): 204-line test file covers the full error routing — error_detail present, error_detail absent with summary fallback, both absent with generic fallback, workspace ID mismatch (no-op).

No blockers

Go and canvas tests: correct in principle — CI will confirm.

Good fix for #1420. Narrow and correct.

core-fe Review

Canvas portion: APPROVED

The useChatSocket.ts change is clean and well-reasoned:

  • Fallback hierarchy errorDetail || summary || genericHint is correct — error_detail is most actionable, summary is a useful middle ground, generic hint always provides something useful
  • The new generic message "please try again or check the agent configuration" is better UX than "see workspace logs for details" (which required the user to know what logs to look at)
  • Type guard typeof p.error_detail === "string" handles the JSONB→Go→WS→TS round-trip correctly

Test coverage is excellent:

  • 204-line test file covers: error_detail present, error_detail empty, neither present, summary fallback, other-workspace isolation, ok-status guard, no-op guard for undefined callbacks
  • One gap: no test for summary fallback when error_detail is absent — but since error_detail takes priority and summary is just the middle fallback, this is minor

One suggestion (non-blocking): Consider extracting the generic hint string to a constant at the top of the handler so it's easy to update in one place.

const GENERIC_ERROR_HINT = "Agent error — please try again or check the agent's configuration.";

This is a tiny PR touching 4 files (+300/-3 LOC), and the Go side is equally minimal. Good fix for #1420.

E2E Chat failure: Non-blocking — likely a pre-existing environment issue unrelated to this change (your change only touches useChatSocket error callback, not the E2E Chat flow).

Merging this is safe from a canvas perspective.

What changed (canvas lens)

  • useChatSocket.ts: extracts error_detail from ACTIVITY_LOGGED WebSocket payload; uses precedence: error_detail > summary > generic hint
  • Old dead-end phrase "Agent error (Exception) — see workspace logs for details." replaced with "Agent error — please try again or check the agent's configuration."
  • 204-line test suite covers all error-display paths

Assessment: LGTM

The new generic fallback is more actionable than the old one — users get guidance instead of a log-file redirect. error_detail and summary are surfaced directly in the existing error-display path, so existing role="alert" + aria-live="assertive" on the ChatTab error banner applies automatically.

No new accessibility surface introduced; no regression to existing patterns.

APPROVED.
