Bamboo reports the following HTTP 400 Bad Request errors when communicating with Bitbucket during certain operations.

  • mirrors.not.supported
  • repository.stash.error.mirror.versionNotSupported


  • Bamboo 6.2 or later
  • Bitbucket Server


When checking the HTTP response received by Bamboo after communicating with Bitbucket, users can see the following:

  "errorCode": "mirrors.not.supported",
  "message": "repository.stash.error.mirror.versionNotSupported"


Mirrors are only supported on Bitbucket Data Center versions. Running a Server licence will generate those messages.


The message can be ignored. You can also upgrade your Bitbucket to a Data Center licence to enable the mirrors feature.
