Hi, I want to connect Mendix with SNS. I am using the AWS Services marketplace module to connect. I am using the Credentials_NewEdit page of the AWS Service module. I want to know what does Identifier and endpoint fields are required. I am providing AWS account ID and service endpoint and all other necessary details but facing an error in making the connection. The error was : Error while validating connection: Could not find operation GetCallerIdentity for version 2011-06-15 (Service: Sts, Status Code: 400, Request ID: 3ebbeeb9-f565-55da-b899-b44f21c02ad5, Extended Request ID: null). Please suggest me a solution. Thanks and Regards, Harshraj Singh
