Summary

When editing an inactive workflow, Edge doesn't seem to respect the default "Screen" value of "None". So, when trying to add a transition - a 'blank' error message is displayed due to the "Screen" field not having a value.

Environment

• Cloud

Steps to Reproduce

1. Navigate to Jira settings > Issues > Workflows; Inactive
2. Click on a status, then click "Add transition"
3. Configure the new transition and try to add the new transition

Expected Results

• The transition is added without issue

Actual Results

• 'Blank' error message is displayed
  

Notes

• This issue only seems to happen in Microsoft Edge, this is not on an issue on Chrome
• For some reason, on Edge, the "Screen" field is empty and will cause a HTTP 400 response
  
  (Screen = NaN)
• Edge is not respecting the "Screen" field's default value of "None"
• When performing the same action in Chrome, the "Screen" field value defaults to "None"
  

Workaround

• Ensure that the "Screen" field has a value before trying to add a transition
• Click on a random transition within the workflow you'd like to edit instead of a status - then click "Add transition"
