Does JIRA Cloud support a full regex functionality in the field validator for the status transition?

[Kent Chiu]

Hi,

We are experiencing an issue with the Regex field validator in the JIRA transition workflow.

Could anyone help identifing why the following Regex fails?

^(?!\s*$)(?!\b(tbd|TBD)\b)(?!\.).*

The Regex enforces the rules not allowing an entry to the field:

- Begins with a "." (period)
- entry with "TBD", or "tbd" only
- Entry with spaces only.

I have tested the Regex using the online Regex validator and it passed the test. However, it failed when I applied to the JIRA transition field validator.

Does the JIRA field validator support the full functionality of Regex?

The text I used for testing is shown in the attachment as an image. It has a rich text format paragraph with bullets.

The error message shows as: the content does not match regular expression  ^(?!\s*$)(?!\b(tbd|TBD)\b)(?!\.).*

I appreciate your help.

Regards,

Kent
