Research direction

Begin at the sidebar's computed path in store-context-D98Bm7Rj.js and trace the data used with GET .../views/?per_page=50 and GET .../views-lite/. Reproduce on an empty project, compare the returned shapes, and verify completion when the Project Views page opens without the TypeError or error boundary.

Description

Bug: Project "Views" page crashes with TypeError: n.find is not a function

Instance: self-hosted, Plane Enterprise Edition (Commercial), v3.1.1 (chart makeplane/plane-enterprise, latest available — confirmed both via /api/instances/ self-check and helm search repo)

Repro steps:

  1. Open any project → click "Views" tab in sidebar
  2. Page shows generic error boundary: "🚧 Looks like something went wrong!"

Environment: fresh project created via public API (POST .../projects/), 0 custom views defined, issue_views_view: true (default)

Console error:

TypeError: n.find is not a function

    at e.useMemo (chunk-ZA36QIGN-b7JuA1sz.js:1:7330)

followed by React Router error boundary catch + duplicate React error #418/#423 (hydration mismatch, secondary symptom of the above).

Notes:

  • Confirmed NOT a backend/API issue — every request in this flow (GET .../views/?per_page=50, GET .../views-lite/) returns 200 with valid (empty) response.
  • Reproduces identically on both v3.1.0 and v3.1.1 (upgraded specifically to test — no change).
  • Root cause looks like a MobX computed value in the sidebar's store-context calling .find() on a value that isn't an array — possibly a shape mismatch between what views-lite (returns raw array) and views (returns paginated {results: [...]}) endpoints return, if the sidebar merges/reads from both without normalizing.
