Error 404: Issue Does Not Exist

Question: Why am I getting a 404 'Issue Does Not Exist' error during synchronisation?

Answer: There are two possible reasons for this error:

  • The issue was deleted in Jira after it was linked to the MS Project task, and the field mapped to Issue key (Text10 by default) now contains the key on an issue that no longer exists. To fix the problem, clear the field, which will recreate the issue, or delete the task.

  • This error can occur because Jira Server/DC 9.0 introduced breaking changes to its REST API, making older versions of Ceptah Bridge incompatible. To resolve the problem, upgrade Ceptah Bridge to version 3.14.6 or higher. If you synchronise the Security Level field, use version 3.15.10 or higher.
