Problem

When transitioning a issue from one state to another, the transition screen does not load.

Instead, the screen becomes gray and the following error is logged to the JS browser console:

1 SyntaxError: JSON.parse: unterminated string at line 1 column 587 of JSON data... (batch.js)

Cause

Transition screen issues of this kind are typically caused by misconfigurations in:

  • Workflows and their transition screens

  • Screens schemes

Diagnosis and resolution

  • Review the workflow assigned to the project for any anomalies

  • Review the transition that is failing and the screen assigned to it and verify the screens are configured properly

  • Change the workflow transition screen to isolate the root cause further
