Bitbucket 2FA status check

[nikolazlatkovic]

Which version of GCM Core are you using?

2.0.157-beta+b11949c7a5 (macOS, .NET Core 3.1.4)

Which Git host provider are you trying to connect to?

• Bitbucket

Can you access the remote repository directly in the browser using the remote URL?

• Yes

Expected behavior

I am authenticated and my Git operation completes successfully.

Actual behavior

I was getting following:

fatal: Error converting value {null} to type 'System.Boolean'. Path 'has_2fa_enabled', line 1, position 95.
fatal: Null object cannot be converted to a value type.

followed by password prompt:
Password for 'https://***********@bitbucket.org':

instead of being authenticated automatically.

After that, I have set up 2FA for that account, repeated the git pull command, was redirected to browser to perform (two-factor) authentication and authorization, and after that all commands were automatically authenticated.

Git remote format is: https://********@bitbucket.org/*******/*******.git

Hi @nikolazlatkovic thanks for reporting this issue! I believe we've already corrected this issue (#126) and it should be available in the next release. Watch this space 😃
