Infinite installation loop of @aws-sdk/credential-providers on startup when AWS_BEARER_TOKEN_BEDROCK is set #6765
Description
Description
OpenCode hangs on startup when the AWS_BEARER_TOKEN_BEDROCK environment variable is set. It triggers a re-installation of @aws-sdk/credential-providers on every single launch, even if the package is already successfully installed.
This becomes a blocking issue if the connection to the npm registry is slow or unstable (e.g., when using a custom registry mirror like npmmirror), causing the CLI to hang indefinitely during the network request.
Verification:
I confirmed that manually modifying ~/.cache/opencode/package.json by changing the version of @aws-sdk/credential-providers from the specific version number (e.g., "3.962.0") to "latest" makes the issue disappear immediately.
Root Cause Analysis:
I investigated the source code and identified the issue in packages/opencode/src/bun/index.ts.
src/provider/provider.tscallsBunProc.install("@aws-sdk/credential-providers")without a version, defaulting to "latest".BunProc.installcompares the installed version inpackage.json(e.g., "3.962.0") against the requested version ("latest").- Since "3.962.0" !== "latest", it forces a
bun addcommand every time, triggering unnecessary network requests.

This issue might be a duplicate of existing issues. Please check:
bun addget stuck #4682: opencode get stuck whenbun addget stuck - Reports similar hanging issues during package installation, though the root cause may be related to your identified version comparison problem.Feel free to ignore if your specific case differs from those issues.

I experienced the same BunInstallFailedError with @aws-sdk/credential-providers on OpenCode v1.1.36 running on macOS.
Environment: AWS environment variables set (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION)
Workaround that worked:
After this, OpenCode starts normally without the installation loop. Can confirm the npm workaround is effective for this version.
