Clone in Sourcetree from tutorial leads to invalid username or password
I am following your Sourcetree tutorial at https://support.atlassian.com/bitbucket-cloud/docs/copy-your-repository-and-add-files/
I am on Windows 10. I am at https://bitbucket.org/MSCPS/bitbucketstationsupplies/src/master/ and click on "Clone", then on "Clone in Sourcetree". Between steps 4 and 5, I get a spinner and then "This is not a valid source path" below the first field in the Clone dialog. When I click "Details" here is the full error message:
Command: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote https://MSCPS@bitbucket.org/MSCPS/bitbucketstationsupplies.git
Output:
Error: remote: Invalid username or password
fatal: Authentication failed for 'https://bitbucket.org/MSCPS/bitbucketstationsupplies.git/'
Considering this is a tutorial it strikes me that the tutorial instructions may have a missed a step? I'd like some guidance on how to progress from here.
