Error reading credentials from stream, 'type' field not specified.

Environment details

1. Create Web application credentials (web server app)
2. OS type and version: macOS 10.15.6
3. Java version: java8
4. google-auth-library version(s): 1.3.0

Steps to reproduce

this is my json file :

{
  "web": {
    "client_id": "xxxxx-xxxxx.apps.googleusercontent.com",
    "project_id": "xxxxx-xxxxx-xxxx",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_secret": "xxxxxx-xxxxx",
    "redirect_uris": ["http://localhost:8888/Callback"]
  }
}

Code example

GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream("/path/to/credentials.json"));
credentials.refreshIfExpired();
AccessToken token = credentials.getAccessToken();
// OR
AccessToken token = credentials.refreshAccessToken();

Stack trace

java.io.IOException: Error reading credentials from stream, 'type' field not specified.

	at com.google.auth.oauth2.GoogleCredentials.fromStream(GoogleCredentials.java:166)

how to solve this problem？

Thanks!

Yes I read this code before I opened issues

but the json file obtained through this tutorial Create Web application credentials (web server app) does not have a type attribute.

It’s exactly the same as below. I didn’t modify any information except sensitive information.

{
  "web": {
    "client_id": "xxxxx-xxxxx.apps.googleusercontent.com",
    "project_id": "xxxxx-xxxxx-xxxx",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_secret": "xxxxxx-xxxxx",
    "redirect_uris": ["http://localhost:8888/Callback"]
  }
}

so I don’t know how to do it
