Summary
This PR ensures that
canonicalise_query_stringshould always return a URL encoded format query string. Currently whenqueryis a table, the value will not be encoded again. This makes the STS assumeRole not working since assumeRole requires a IAM ARN which contains colon that should be URL encoded. Calling STS assumeRole will return signature not match error without the PR's fix.
