Problem

After trying to create a new issue through REST API, the following error appears in the terminal:

{
"errorMessages": [
"Internal server error"
],
"errors": {}
}

Diagnosis

Start by making sure the json data are valid by referring the tutorial page.

You may also refer to atlassian-jira.log for a more complete error message or likely a java stack trace to help determine the root cause.

Additionally, you can enable HTTP access logs and HTTP dump logs on Logging and profiling page and run a test - this will create atlassian-jira-http-access.log and atlassian-jira-http-dump.log files. Note that this will produce a lot of logging and we advise against leaving it enabled.

Cause

The problem is the JSON data are not completely correct or Jira is unable to generate a valid response for the request.

Resolution

Refer to the JIRA REST API official documentation for more examples.
