即使设置环境后也无法加载默认凭据

Question

I set up env varible VISION_KEYFILE_JSON with key values of the vision app, when I console

console.log(`key: ${process.env.VISION_KEYFILE_JSON}`);

It gives the key, when executing the code

const client = new vision.ImageAnnotatorClient({ projectId: config.google.project_id});

I got the following error

Error: Could not load the default credentials. Browse to https://developers.google.com/accounts/docs/application-default-credentials for more information.

How to solve this?

Answer 1

You need to also set GOOGLE_APPLICATION_CREDENTIALS for Application Default Credentials to work. I think setting it to the same value as VISION_KEYFILE_JSON is correct.
