AWS Sign V4 calculation error

When I use Yaak to POST a request to AWS Beckrock Claude model with a modelId “

us.anthropic.claude-haiku-4-5-20251001-v1:0“, it gives a error “

"message": "The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method.

Seems the colon in the modelId was not correctly encoded.
