Issue Summary

Applying the code suggestion can fail with a generic error when the FILE_EDIT hook rejects the commit. This can be caused by a custom hook or a Yet Another Commit Checker Plugin (YACC).

Steps to Reproduce

Check the community ticket for more details: https://community.atlassian.com/t5/Bitbucket-questions/Are-code-suggestions-broken-in-Bitbucket-7-4/qaq-p/1453200

Expected Results

• The displayed error message should show detailed information about the reason of rejecting commit.
• It should be possible to apply the suggestion with a second try.

Actual Results

• The displayed error message doesn't give the user any clue what's the reason of the failure.
• After the failure, the apply button is disabled and the user can't re-apply the suggestion.

Workaround

Disable the custom FILE_EDIT hook or disable the Yet Another Commit Checker Plugin.
