Zyyeric opened a new issue, #4992: URL: https://github.com/apache/opendal/issues/4992
### Describe the bug When attempting to use the GCS storage service, opendal fails to load the application default credential from ADC Well-known places (https://cloud.google.com/docs/authentication/application-default-credentials). I did realize that this is implemented within the load_via_well_known_location() in reqsign/src/google/credential.rs. However, while having the ADC stored within [HOME/.config/gcloud/application_default_credentials.json], I ended up getting this error. ``` Unexpected (temporary) at stat, context: { called: reqsign::LoadCredential, service: gcs, path: file.txt } => loading credential to sign http request, source: error sending request for url (http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/token?scopes=https://www.googleapis.com/auth/devstorage.read_write) ``` ### Steps to Reproduce Obtain ADC through gcloud CLI ``` gcloud auth application-default login ``` which shall output ``` Your browser has been opened to visit: https://accounts.google.com/o/oauth2/auth?... Credentials saved to file: [HOME/.config/gcloud/application_default_credentials.json] These credentials will be used by any library that requests Application Default Credentials (ADC). ... ``` Then, create a basic opendal operator, and send a head request. ```` let mut builder = opendal::services::Gcs::default(); builder .bucket("my-bucket-here"); let op = Operator::new(builder)? .layer(LoggingLayer::default()) .finish(); // Check if the file exists by querying its metadata match op.stat("my-path-here).await { Ok(metadata) => { // If successful, print the metadata or a success message println!("File exists! Metadata: {:?}", metadata); } Err(e) => { // If there is an error, print it eprintln!("Error accessing file: {}", e); } } ```` ### Expected Behavior Opendal shall load the credential and returns the metadata of the file stored in GCS ### Additional Context _No response_ ### Are you willing to submit a PR to fix this bug? - [ ] Yes, I would like to submit a PR. -- This is an automated message from the Apache Git Service.
