Import from Github failed and the repo just stuck there

[Deleted user]

Try to migrate some of my repos from GitHub to Bitbuckets and then this error page shows up:

And the error code is: 78ee87a5be96400b83ab38e8d945e609

What's worse is I tried to delete the repo and re-import it, however I can't access the "Settings" section of the repo, where the delete button locates at. Everytime I go there the same error page just shows up.

Any idea? Thanks!
