Issue Summary

Creating or updating a high number of issues via the /rest/api/3/issue/bulk endpoint leads to 404 errors.

Steps to Reproduce

1. Use the /rest/api/3/issue/bulk endpoint to create/update a significant amount of issues

Expected Results

The request completes and a 2XX status code is returned.

Actual Results

The request fails with a 404 status code.

Notes

While it is true that the request returns a 404, all the issues will be correctly created.

This has been reproduced when creating/updating over 200 issues, but depending on the Jira configuration it could occur with a smaller payload.

This problem occurs for the following reason:

• the /rest/api/3/issue/bulk request is being processed in a synchronous way
• when the request payload contains a high number of issues to be created (e.g. 200), this leads to a 404 http status code being returned
• even if the app requesting the endpoint receives a 404, all issues are created by Jira

When using the second version of the api /rest/api/2/issue/bulk the error returns as HTTP 504.

Workaround

Reducing the number of issues updated or created will prevent this issue from occurring.
