Uploading attributes with not allowed characters give unclear errors

[marijevdgeest]

How to Reproduce

When you want to upload a model in Molgenis 10, but you have accidentally a space in an attribute name in the attributes sheet, sometimes Molgenis gives an unclear error:

500
Handler dispatch failed; nested exception is java.lang.StackOverflowError

But not all the time, once I got the normal error that mentioned there was a not allowed character and for which attribute, I wasn't able to pinpoint why this happend.

Expected behavior

When uploading a model with mistakes normal errors are thrown.

Observed behavior

Unclear 500 error
