Editing an issue through the filter issue gadget throws an error

Summary

When editing an issue through the filter issue gadget it throws the error:

Error instantiating webwork.multipart.parser.class: com.atlassian.jira.web.JiraMultipartRequestWrapper(original message: null)

Steps to Reproduce

1. Create a new filter that will return any valid issue.
2. Create a new dashboard
3. Add a filter issue gadget and select the filter created in the first step.
4. Right side of any issue, select the three dots button and Edit.
5. In the new edit window, select Update.

Expected Results

The issue would be updated and the screen return to the dashboard.

Actual Results

The issue is update but the UI throws an error.

Notes

This issue is sometimes caused by a permission configuration issue. If you see this issue, ensure the Jira user has read/write/execute permissions and ownership of your installation work/ and temp/ folders then restart. If that does not resolve it, then this bug is the cause and the ticket can be edited in a new tab or from a different screen as mentioned in the workaround section.

Workaround

Manually back to the dashboard or open the issue and edit there.
