Is there an existing issue for this?

Current behavior

When using the Query Parameters table for an HTTP method that uses Amazon Signature for authentication, the request will fail to authenticate, with the response message:

"The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

The Canonical String for this request should have been <calculated string>"

It appears that query parameters from the table are not being properly appended to the canonical URL string that is used in the calculation of the signature. In contrast, manually appending the query parameter directly in the URL field works correctly.

Steps to reproduce

Create HTTP request for an API endpoint that requires Amazon Signature authentication. Confirm it is working.
Add a query parameter to the Query Parameters table. Request should fail.

Environment

Production

Version

Cloud

@nmccrea, I wasn't able to reproduce the issue. Have you checked the query parameters and the body type application/x-www-form-urlencoded that you're accepting through that API?
