error authentication failed while cloning repository

[Hans Christian]

hello i encountered an error while im about to clone my repository on bitbucket.

Command: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote https://cloudcompkel2@bitbucket.org/cloudcompkel2/1902-line.git
Output:
Error: fatal: ArgumentException encountered.
An item with the same key has already been added.
fatal: ArgumentException encountered.
An item with the same key has already been added.
remote: Invalid username or password
fatal: Authentication failed for 'https://cloudcompkel2@bitbucket.org/cloudcompkel2/1902-line.git/'

i dont know whats wrong with the sourcetree because this is my first time using bitbucket.

The issue is related to Sourcetree and not to GIT or GIT Credential manager.

if anyone can help me i would be thankful.
