Production React app authoring agent silently fails to start

  1. We have a production-blocking Retool React App authoring issue isolated to the AppGen authoring sandbox.

    Organization: TCWGlobal
    App: TCW AR Collections
    App UUID: 79195038-95ca-11f1-a0c1-472b48a4b29f
    Published URL: https://tcwglobal--tcw-ar-collections.retool.app
    Current published baseline: updated_at 2026-08-25T18:51:20.156Z
    Current published commit: 7cc98de35a01a1c0005fd4526aebea6e90775a5d

    Observed behavior:

    1. The authoring request is accepted and initially returns state “running” with a generation ID.

    2. The generation then terminates silently.

    3. Activity status returns:

      • active: false

      • state: NO_ACTIVE_GENERATION

      • latestAgentMessage: null

    4. The thread stream contains zero persisted messages.

    5. No requested file changes are applied.

    6. No approval or human-in-the-loop request is pending.

    This has happened four times across three threads, including the following existing threads:

    • e9b6fba1

    • e431b4d1

    The failure persists even with a minimal single-file request. Retool’s other connector capabilities continue to work normally: get_app, file listing, file reading, and read-only database access all respond successfully. The problem appears isolated to starting the React App authoring generation worker.

    An earlier attempt also returned “token introspection rate limited,” which may be related.

    Could Retool please:

    1. Inspect the generation-worker and token-introspection logs for this app and organization.

    2. Confirm why the worker accepts a generation request but exits without producing or persisting a message.

    3. Restore the authoring sandbox.

    4. Confirm whether the existing branches are safe to resume or whether a new branch is required.

    No production data was changed and nothing was published during these failed attempts. The published application continues operating normally; only further code authoring is blocked.
