Unable to export repositories with pull requests that have resolved comments

XMLWordPrintable

      Issue Summary

      When exporting repositories via `POST <bitbucket_url>/rest/api/1.0/migration/exports`, if the repository contains pull requests with resolved comments where the resolver_id is `null`, the export fails. 

      Note: This behaviour was introduced in BB 8.19.6. BB 8.19.5 is not affected.

      Steps to Reproduce

      1. Create a resolved comment on a pull request
      2. Modify the resolver_id to be null in the database e.g.:
      update bb_comment_thread set resolver_id = null where id='62';
commit;

            3. Run an export for this repository via POST <bitbucket_url>/rest/api/1.0/migration/exports

      Expected Results

      Export completes successfully with resolved status

      Actual Results

      The below exception is thrown in the atlassian-bitbucket.log file:
