Thanks for stopping by to let us know something could be better!

PLEASE READ: If you have a support contract with Google, please create an issue in the support console instead of filing on GitHub. This will ensure a timely response.

Please run down the following list and make sure you've tried the usual "quick fixes":

• Search the issues already opened: https://github.com/googleapis/google-cloud-java/issues
• Check for answers on StackOverflow: http://stackoverflow.com/questions/tagged/google-cloud-platform

If you are still having issues, please include as much information as possible:

Environment details

1. Specify the API at the beginning of the title. For example, "[vision]: ..."). General, Core, and Other are also allowed as types
2. OS type and version: windows 10
3. Java version: GraalVM 21.0.1
4. Version(s): vertex 0.1.0

Steps to reproduce

1. Use example here

2. It can't authenticate. I set GOOGLE_APPLICATION_CREDENTIALS env var pointing to the service account json.

Are you able to verify that the credentials pointed to by GOOGLE_APPLICATION_CREDENTIALS are actually valid and have permissions to access the API?

I confirmed. The ADC is working. But the GOOGLE_APPLICATION_CREDENTIALS not. I double check with others as well. Others can reproduce this with GOOGLE_APPLICATION_CREDENTIALS way. @meltsufin @ZhenyiQ

[meltsufin]

@ZhenyiQ has been able to reproduce this issue. @blakeli0 PTAL.

I also encountered the same issue, and in the end, I was able to temporarily bypass this issue using Transport.REST. Hope this helps @SetoKaiba

You can use ADC for authentication. You can still use the sdk.

Thanks @SetoKaiba ! This is indeed a bug in the vertexai sdk. We will push a new version to resolve this. Thanks for bringing this to us!

@blakeli0 @ZhenyiQ @meltsufin Should the defaultScopes be applied to the method public VertexAI(String projectId, String location, GoogleCredentials credentials) as well?
