I could be wrong but maybe this might help: #968 (comment)

@SihengCui when you created the secret, where xxxx plain text or base64 encoded ? It should be the latter, or you use stringData to provide plain-text and the Kubernetes will encode it. Above mentioned PR improves our documentation as passwords are not supported anymore, but instead it must be a token.

emmm.. Do you mean that the password field is filled with the token string? But the git repo is a private Bitbucket. It seems that there is only password. In this case, is there any way to pass the certification?

I have never used BitBucket, but seems like will need some (doc?) changes based on https://support.atlassian.com/bitbucket-cloud/docs/use-oauth-on-bitbucket-cloud/#Cloning-a-repository-with-an-access-token. @SihengCui can you try what happens when you put x-token-auth as username into the secret and your access token as password?

There are something different with git repo using HTTP or HTTPS protocol.
I chose a non-existing domain as my repo address git.sihengcui.com.

After that I just modified http to https.
url: https://git.sihengcui.com/scm/serverless-example.git
It did not prompt "Unsupported type".

Could this be the cause ?

I put access token as password. And success pull the private repository from my github. So I am sure the format of the secret is correct. When the url is replaced with http://bitbucket.xxxxx, even if the username and token are not replaced, a 401 authentication error should be returned instead of Unsupported type.

From grooming:

• We do not want to send username/password credentials using a cleartext protocol like HTTP. We should improve the error message, though. -> #1131
• We need to verify https://support.atlassian.com/bitbucket-cloud/docs/use-oauth-on-bitbucket-cloud/#Cloning-a-repository-with-an-access-token. Today, when somebody clones using HTTPS with username/password, then we use Git's credential helper. But we don't know how this maps to the Git clone command. To be checked, fixed if necessary, and updated in the docs if appropriate. -> #1132
• We should also check if somebody really does what BitBucket does = putting credentials into the .spec.source.url field of the Build. This will maybe work, but we will also likely leak the password in the logs of the source-default step. Though, it should generally not be recommended to do this at all because the password is then unencrypted in etcd. Maybe also worth a hint in the docs. -> #1133

Hi @SihengCui, if possible, can you help me by providing the exact yaml files you used as a step to reproduce this problem?
I want to try fixing this but I notice you've added a few 'xxx' in parts of the yaml file above and I'm not sure which values to add there.

That's a private git address on an internal network. If you need to reproduce the problem, just request any of the HTTP repositories. NOT https

Awesome, I'll do that. Thank you!
