This is not the issue which caused by Azure devops. No matter https://xxx.visualstudio.com
, or the URL which like dev.azure.com
, they should all available git source.
For me, I just try with multi different git URLs, and found the few of URLs are failed with same error with you. But it prompt This is a git repository
after I exit the SourceTree and re-configure the clone with same URL which encountered the error previously.
This seems be the most common Sourcetree problem which encountered by many users, not just the URL of azure devops that you occurred.
Check this thread, and try with its recommend way:
Open source tree, Tools -> Options -> Click on Git Tab -> Update
Embedded Git.
Or, consider the method I used: exit the Sourcetree, and re-configure the clone with same URL. (Not recommend since this can not permanently solve this issue)
