I am trying to import some issues to Jira Product Discovery from another system. I have created the import file, mapped the value types, but getting this error for every issue:
Issue can't be created due to the error/s [ Specify a number for the custom field (below 100,000,000,000,000)
The error does not specify which field is causing it. I suspect it should be related to a number field, but I am not aware importing any number type of data.
My field mapping looks like this - no number fields there.

What is wrong here?
