DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

AWS credential failures say what went wrong

You'll notice
Useful3 Signal1
Bedrock

AWS credential problems now come with one clear message instead of a raw SDK error.

What

When Bedrock or Vertex request signing cannot get AWS credentials, you now get one clear message instead of a raw SDK rejection.

Details
  • The provider chain is awaited inside a try/catch and any failure is rewrapped as a typed error with a fixed message.
Evidence

Failed to resolve AWS credentials from the credential provider chain.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
