Summary
Symptoms
When editing or transitioning an issue, the user omits some required information. While we expect JIRA to display a "<fieldname> is required." message, this is not seen. This can cause confusion for the end user, who is not able to understand why their change is not accepted by Jira.
Diagnosis
Your Jira is encountering this error if:
You're using Microsoft IIS as a proxy
Bypassing that proxy causes the problem to stop
Cause
This is caused by a security feature in Microsoft IIS that prevents JSON error messages from being served to clients in case they contain sensitive information.
Solution
Resolution
To resolve this issue, go to the Error Pages console in IIS and change the Error Responses to Detailed Errors instead of Detailed Errors for Local Clients and Custom Error Pages for Remote Clients. More information can be found at Stack Overflow.
As IIS is a third-party product, this document is provided as advice only. Atlassian does not provide support for integrating JIRA with third-party products.
