Credentials password is null

What is version of KubeSphere DevOps has the issue?

dev-v3.3.0-alpha.1-d92409f

How did you install the Kubernetes? Or what is the Kubernetes distribution?

What happened?

When creating a github (Code Repository) pipeline, the returned certificate password is an empty string, and the project list cannot be obtained correctly.

Relevant log output

No response

Additional information

When the return value of the API("kapis/devops.kubesphere.io/v1alpha3/devops/testv8rd7/credentials/password-null?content=1") ) is like this
{
 ....
 "data": {
  "id": "xx",
  "password": "xx",
  "username": "xxx"
 },
 "type": "credential.devops.kubesphere.io/basic-auth"
}
will get the desired result, but when password is set to empty, no information will be obtained.
{
 ....
 "data": {
  "id": "xx",
  "password": "",
  "username": "xxx"
 },
 "type": "credential.devops.kubesphere.io/basic-auth"
}

Start by reproducing the GitHub Code Repository pipeline case against the kapis/devops.kubesphere.io/v1alpha3/devops/testv8rd7/credentials/password-null?content=1 endpoint. Compare behavior when the credential password is populated versus an empty string, and confirm that the empty-password response still allows the project list to be obtained.
