Hi @etwardowska ,

This can happen when the user is deleted or any such cause wherein the profile page of the user is not available.

To remove this error, I would suggest that before adding any filed, you can check if the value exists with ?has_content or you can assign a default value with Freemaker wherein no redirection is carried.

Documentation for the same:

https://freemarker.apache.org/docs/dgui_template_exp.html#dgui_template_exp_missing_default

https://freemarker.apache.org/docs/ref_builtins_expert.html#ref_builtin_has_content

 

Please Give Kudos if you find this post useful and also mark this as Accepted Solution if this is the required solution.
