## Summary The GCS storage driver currently uses the deprecated `google.CredentialsFromJSONWithParams` function, which prevents upgrading to newer versions of the Google Cloud SDK due to `golangci-lint` staticcheck failures. ## Background In !2779, we reverted a version upgrade because it exposed deprecation warnings: ``` storage/driver/gcs/common.go:276:16: SA1019: google.CredentialsFromJSONWithParams is deprecated storage/driver/gcs/common.go:304:16: SA1019: google.CredentialsFromJSONWithParams is deprecated ``` The deprecated function has a potential security risk as it doesn't validate credential configuration when accepting credentials from untrusted sources. ## Tasks - [ ] Research the recommended replacement for `google.CredentialsFromJSONWithParams` - [ ] Update `storage/driver/gcs/common.go` to use the secure credential validation approach - [ ] Ensure credential configuration is properly validated - [ ] Test GCS storage driver functionality with the updated implementation - [ ] Re-apply the version upgrade that was reverted in !2779 ## Files Affected - `storage/driver/gcs/common.go` (lines 276 and 304) ## References - Revert MR: !2779
