JIRA "next gen" board user picker issue

Question

I can not use the next gen board, everytime I try to create an issue I receive the following message:

Something's gone wrong

Product Owner: User 'admin' is not valid for this user picker

It seems It want to add a labeled role I have in another project rather than my actual user name.

This sounds exactly the an issue I'm having!

We have no custom fields in the project in question, but the field at the front of our error did exist in a project we deleted recently.

@Robin Sarfati did you ever resolve the issue?

Hi Robin,

Sorry, I should have specified.
The custom fields are located on Jira Settings > Issues > Custom fields.
There you can check if the custom field has a default value by clicking on ... > Configure > Default value.

Regards,
Angélica
