structuredDiffForFile function returns incorrect results

Hi there, I am using structuredDiffForFile method from GitDSL. I am using this function within the following code snippet:

function claimsToUpdateDocumentation() {
  let claimsToUpdateDocumentation = false
  danger.git.structuredDiffForFile(`${docsFolder}/CHANGEPLAN.md`)
    .then((diff) => {
      diff.chunks.forEach(chunk => {
        chunk.changes.forEach(change => {
          if (change.type === "add") {
            const offence = regexPattern.exec(change.content)
            if (offence) {
              claimsToUpdateDocumentation = true;
            }
          }
        })
      })
      return claimsToUpdateDocumentation;
    })
}

I got inspired about the usage of this method from metaphysics dangerfile.ts. Every-time danger is run on our CI (on premise BitBucket server) against a PR it gets the diff for CHANGEPLAN.md from previous PR. Example:

danger pr https://company.merck.com/projects/foo/repos/boo/pull-requests/2607

structuredDiffForFile returns me the diff of CHANGEPLAN.md from PR #2606 instead of returning diff from PR #2607.

Am I using structuredDiffForFile incorrectly? Or is it a bug?

Version 9.2.1 (node_modules/.bin/danger --version: 9.2.1) works properly with my simple project:

DANGER_BITBUCKETSERVER_HOST=http://localhost:7990/bitbucket DANGER_BITBUCKETSERVER_USERNAME=admin DANGER_BITBUCKETSERVER_TOKEN=ODIyNDUyOTIxMDAwOt5F4JwwCowf7nCX1ogkY9ybm+bd node_modules/.bin/danger pr http://localhost:7990/bitbucket/projects/PROJECT_1/repos/rep_1/pull-requests/2/overview

Danger: ✓ passed review, received no feedback.

dangerfile.js:

danger.git.modified_files.forEach(file =>
  danger.git.structuredDiffForFile(file).then(diff => {
    console.log(diff.chunks[0]);
  })
);

I will try to test it on an instance of Bitbucket in my company.

@platan I figured out that the problem was in our code 🤦‍♀️, so yes v9.2.1 with #871 solves the problem indeed! Sorry for confusion and thank you for help with resolving this issue
