When I trying to deploy some code to aws lamda using serverless framework, i got this exception in cloudformation logs
Resource handler returned message: "null (Service: Lambda, Status Code: 403, Request ID: 6d65524e..., Extended Request ID: null)" (RequestToken: 0e02ad46-c93c-2935...., HandlerErrorCode: GeneralServiceException)
How I can deal with it? I using root account to deploy. (I know that is bad :) )
Try send email to Amazon tech support. Your account may be suspected, (you need approve billing info for example ). This was helpful in my case
