title: Databricks Repo with Azure DevOps - 400 Bad Request when trying to add repo
body: <p>when trying to use the databricks Repo feature with AzureDevOps, I am not able to add a repo to my databricks workspace <a href="https://i.stack.imgur.com/42hPn.png" rel="nofollow noreferrer">add repo</a> and I am getting a Bad Request as Response <a href="https://i.stack.imgur.com/0h5gd.png" rel="nofollow noreferrer">error message</a>.
  Under User settings -&gt; Git Integration -&gt; Git Provider I have selected Azure Devops Services and in advanced settings Notebook Git Versioning is enabled.</p>
  <p>I tried with a different browser, aswell as in private mode. In addition I tried to delete my cookies, but still got the same error. The integration to GitHub with a PAT works fine. I am also able to sync notebooks to the Azure DevOps repository, but the repo feature itself is not working.</p>
  <p>I work in a corporate environment and we use single sign on with Azure Active Directory to authenticate to the Workspace. I really dont have an idea what causes the issue.
  My only guess is that something AD authentification related is not set properly.
  <strong>Sometimes</strong> when trying to access the workspace via the azure portal I receive the message that my account has no Contributer or Owner Role on the workspace <a href="https://i.stack.imgur.com/sjjOE.png" rel="nofollow noreferrer">role warning</a>, which is strange since I am an admin in the Databricks workspace. After clicking on sign in with AzureAD I receive the warning: AADSTS90015: Requested query string is too long <a href="https://i.stack.imgur.com/tYJ5f.png" rel="nofollow noreferrer">query string warning</a>. However if I click back in the browser and click again on sign in with AzureID I am able to access the workspace.</p>
