There was an application error uploading custom attachment.

Hi Everyone, 

Is there any known issue for custom attachment field for Offboarding/Onboarding process with the latest release?

We created a custom task with attachment field. We can browse and upload the form from the task page, but when we try to click submit we encounter this error " There was an application error."
