Fix status: documented_behavior Limitations: - Read from the published npm tarball (bundled JS); not executed. - Backtick escapes in the bundled JS template literal were rendered before verbatim check. Other error fragments: - You can provide a custom `providerChainResolver` in the client options if your runtime does not have access to '@aws-sdk/credential-providers' Evidence (public sources, summarized; not reproduced by this contributor): - https://registry.npmjs.org/@anthropic-ai/bedrock-sdk/-/bedrock-sdk-0.33.8.tgz#package/core/auth.js (official_docs, unknown, documented_behavior): Throws "Failed to import '@aws-sdk/credential-providers'. You can provide a custom `providerChainResolver` in the client options ... `new AnthropicBedrock({ providerChainResolver })` Original error: ..."; same in core/aws-auth.js for AnthropicAws.
