      Notes

      There could be other strings leading to this behaviour. The exact description causing the problem can be detected by using the following rest API and inspecting the description field in the resulting Json.

      rest/api/1.0/projects/<project>/repos/<repository>/pull-requests/<pull request id>
      

      Workaround

      Update the pull request by editing the description using the REST API

      1. Get the current version field from the GET rest/api/1.0/projects/<project>/repos/<repository>/pull-requests/<pull request id>
      2. Update the pull request by using the same endpoint (with PUT as a method)
        curl --user username:password -H "Content-Type: application/json" --data @input.json -X PUT <Bitbucket_URL>/rest/api/1.0/projects/<project>/repos/<repository>/pull-requests/<pull request id>
        

        Where the input.json file contains the following and version is the same value as the one returned by the request above:

        {
            "version": 6,
            "description": "expected description"
        }
