linear_app: surface GraphQL errors instead of crashing - #21903

Linear answers a rejected query with HTTP 200, `data: null` and a populated `errors` array, but `post()` destructured `data` blindly, so every failure reached the user as `TypeError: Cannot read properties of null` with the real message discarded — in `listIssues`, `getIssue`, `getProjectUpdateGraphQL`, `listProjects`, `listProjectUpdates` and `getComment` alike. Check `errors` in `post()`, the single choke point those six share, and raise a ConfigurationError instead. `makeAxiosRequest` is left alone: `isAdmin()` in the sources' webhook base calls it directly and falls back to polling when it fails, which throwing would turn into a broken deploy. Linear keeps the actionable part of a validation failure nested under `extensions.validationErrors` while the top-level message stays a generic "Argument Validation Error", so flatten that tree into the message: Argument Validation Error (team.id.eq: eq must be a UUID) Also fix the `teamId` prop description, which promised that a team key works. It does not — the value goes into an `id` comparator that requires the UUID, and `DEV` in place of it is what produced the crash above.

- Around line 119-130: Update flattenValidationErrors so both the top-level
validationErrors argument and recursive children values are normalized to an
empty array when they are null or otherwise not arrays before calling flatMap.
Preserve the existing property-path construction and recursive flattening
behavior for valid arrays.
In `@components/linear_app/linear_app.app.mjs`:
- Around line 353-354: Update the GraphQL error handling in post() so only
user-fixable validation errors become ConfigurationError; propagate rate-limit
and other non-configuration API errors using their existing retryable/error
semantics, while preserving the current formatted message for configuration
failures.
- Line 16: Update the teamId field description to remove the list-selection
guidance, state that it requires a Linear team UUID, include an accepted UUID
example, and identify it as the team’s id field from a Linear API response;
retain ENG-123 as an invalid example.

Thirteen cases over common/utils.mjs, the first tests in components/. The formatGraphQlErrors ones pin the payload Linear actually returns for a team key in place of a UUID, nested constraint and all, so a regression shows up as a lost message rather than as another opaque crash. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Keep non-configuration failures retryable: `post()` raised ConfigurationError for every populated `errors` array, so a `RATELIMITED` reply halted the workflow as misconfigured instead of backing off. Linear marks what a caller can act on with `extensions.userError`, so reserve ConfigurationError for the errors where all of them are, and throw a plain Error otherwise. Guard `flattenValidationErrors` with `Array.isArray`. A default parameter only covers `undefined`, so a null `validationErrors` or `children` threw the very TypeError this change exists to remove, discarding the message along with it. Name a UUID in the `teamId` description and drop the vaguer "the UUID the API returns", while keeping the mention of the dropdown, which is how anyone configuring the action in the UI actually picks a team. Document the three functions with JSDoc, covering what Linear puts in a failed response and how the two error classes differ. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The context it builds from `app.methods` stands in for what the platform assembles around a component at runtime, which is worth stating where someone reading the suite meets it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The Docstring Coverage check reports only the aggregate result. It provides no function names, file locations, or annotations. I verified that these four declarations have preceding JSDoc blocks:
Therefore, none of those four is visibly undocumented. The likely cause is a scanner classification issue. It may count an inline callback as a touched function, or it may fail to associate JSDoc with an object-literal method or arrow-function assignment. The aggregate result does not show which case occurred. The warning is not actionable as reported. It needs per-function output before a specific docstring can be added or corrected. You are interacting with an AI system. |

Summary
Search Issuesfails withTypeError: Cannot read properties of null (reading 'issues')whenever Linear rejects the query. Linear answers a rejected query with HTTP 200,data: nulland a populatederrorsarray, butpost()destructureddatablindly, so the real message was discarded and the user got a stack trace pointing at the app file.Five other methods share the same choke point and the same crash:
getIssue,getProjectUpdateGraphQL,listProjects,listProjectUpdates,getComment.The fix checks
errorsinpost()and raises aConfigurationError.makeAxiosRequestis deliberately left alone —isAdmin()in the sources' webhook base calls it directly and falls back to polling when it fails, which throwing would turn into a broken deploy.Linear keeps the actionable part of a validation failure nested under
extensions.validationErrors, arbitrarily deep, while the top-level message stays a genericArgument Validation Error.formatGraphQlErrorsflattens that tree into the message.Also fixes the
teamIdprop description, which promised that a team key works. It does not — the value goes into anidcomparator that requires the UUID, and passingDEVis exactly what produced the crash.Before / after
Calling
Search IssueswithteamId: "DEV":TypeError: Cannot read properties of null (reading 'issues')ConfigurationError: Argument Validation Error (team.id.eq: eq must be a UUID)Testing
Ran the actions against a live Linear workspace:
Search IssueswithteamId: "DEV"→ theConfigurationErroraboveSearch Issueswith the team's UUID → 50 issuesSearch Issueswith onlyassigneeId→ 5 issuesList Projects→ 20 projects, no regression on the success pathGet Issuewith a non-existent id →ConfigurationError: Entity not found: Issue(it crashed the same way before)npx eslint components/linear_appreports 0 errors. The 9 remaining warnings are pre-existing source-naming ones onmaster, untouched here.Error classes
ConfigurationErroris reserved for the case where every error carriesextensions.userError, which is how Linear marks what the caller can act on. Anything else —RATELIMITED, a server fault — throws a plainErrorso it stays retryable rather than halting the workflow as misconfigured.Tests
19 tests, the first under
components/.common/utils.test.mjscoversformatGraphQlErrorsandbuildVariables;linear_app.app.test.mjscovers the error classification inpost().These need #21904 to run.
npm testis broken onmaster— jest 29 rejects.jsinextensionsToTreatAsEsm— and the defaulttestMatchdoes not discover.mjsbesides. That fix is out on its own in #21904, since it is a repo-wide change with nothing to do with Linear; the tests stay here, with the code they cover. Merge order does not matter — this PR is correct either way, its tests simply do not execute until #21904 lands.Until then they run against a config passed on the command line:
Overlap with open work
#21569 and #21573 touch seven of the same files. There is no functional overlap — they add a
fieldsprop to trim response payloads, this fixes error handling — but both bumpcomponents/linear_app/package.json, and #21573 expects0.12.0where this PR takes0.11.2. Happy to rebase onto whichever lands first.components/linearspreadslinearApp, so it inherits the fix once its own components are republished. Left alone here, since #21569 already edits those files.Checklist
