Jira Forms File Upload Works in Sandbox but Fails in Production
Hi Community,
I’m running into a strange issue with Jira Forms (ProForma) in Jira Service Management and need help figuring out why there’s a difference between our sandbox and production setup.
Here’s the situation:
-
I created a Jira Form with a File Upload question.
-
When a customer uploads a file in production, they get:
Error uploading attachment
An error occurred when uploading an attachment
But in our sandbox environment, the exact same setup works fine — customers can upload files through the form without any errors.
What I’ve already checked:
-
Attachments are enabled in System → Attachments in both environments
-
File size limits and allowed file types are the same
-
Customers have permission to add/view attachments in Customer Permissions
-
Tested with small files (txt, png) — same result
-
Works when an agent uploads files in production — fails only for portal customers
What I suspect:
-
There might be a difference in permission schemes, request type field configuration, or project type (company vs team-managed) between sandbox and production.
Has anyone seen this before?
What settings should I compare between sandbox and production to find the root cause?
Is there anything specific about Jira Forms’ file upload question that could behave differently between environments?
Thanks for any guidance — I’d like to avoid switching to the native attachment field if possible since the form upload works perfectly in our sandbox.
