Http GET method gives unmatched signature exception

[sameerrathore]

Firstly, Thanks for the saviour here.

when I try to use it for a Http GET invocation, I am getting:

ca.ryangreen.apigateway.generic.GenericApiGatewayException: {"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."} (Service: execute-api; Status Code: 403; Error Code: InvalidSignatureException;

Any help will be appreciated.

Regards,
Sameer
