Maestro Case Plan Debugging Error: WorkflowCompiler PackagerFlags.json not found / AppTasks 170000 NotFound

Hello Community,

I am hitting a persistent compilation error when trying to run a “Debug on Cloud” session for a Maestro Case Plan template (PharmaComplaintCase).

The Errors:

  1. In the execution log panel:
    WorkflowCompiler: "EscalationApp" PackagerFlags.json file not found for project /tmp/.../Input/EscalationApp
  2. In the Instance Management incident panel:
    Failure in the AppTasks request - (170000) Error AppTasks request failed with status NotFound. Response body could not be parsed: Unexpected character encountered while parsing value: S. Path '', line 0, position 0.

What I have done so far:

  • I had a draft/unpublished app called EscalationApp bound via a .local resource path.
  • I have completely deleted that app card from the visual canvas timeline.
  • I went to the UiPath Apps homepage and permanently deleted the draft app container from my personal workspace.
  • I have carefully checked and cleaned the Raw JSON Code View (</>) bindings array. The text string "EscalationApp" is completely missing from the bindings list now (we replaced it with a valid tenant app Shared_EscalationApp_Final).

Despite the bindings being 100% clean, the Cloud Compiler/Packager is still caching a dependency link under the hood to the deleted app, looking for its PackagerFlags.json file inside the temporary worker container (/tmp/), failing to find it, returning a text string error, and crashing the JSON parser.

Has anyone found a way to force-flush or re-provision the project metadata folder when Studio Web refuses to release a deleted App reference cache? or any other way

Thank you!

Try opening the solution in Desktop Studio.
Once opened, try deleting all the temporary folders which starts with . (dot) like .local.

Once done, save to cloud and try from Studio Web again.
