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 request signing keeps query strings

You'll notice
Useful4 Signal2
Bedrock

AWS requests with query parameters are now signed correctly and stop being rejected.

What

Requests to AWS endpoints with query parameters are now signed with those parameters included, so signatures over such URLs should match instead of being rejected.

Details
  • The request-to-sign conversion copies the URL's search parameters into a query object rather than dropping them.
  • The Bedrock credential chain helpers also accept a logger, passed to both the node provider chain and the inner client config.

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