AWS Cloud formation always failed when I try to add new route to gateway

Question

I tried 7 times now but still failed. I'm adding a new route endpoint to my API gateway. I've made the required changes on the cloud formation file and upload it to AWS.

Every try, I got the following error, I don't know how to fix it.

'comp/*/*' is not a valid method path. Method paths can be defined as
{resource_path}/{http_method} for an individual method override,
or */* for overriding all methods in the stage. 
(Service: AmazonApiGateway; Status Code: 400; Error Code: BadRequestException; 
Request ID: 0878sd34-4555-987s-3332-8dfg7d8f9;
 Proxy: null)

Here's a part of the cloud formation file.

As you can see in the method settings section. The HttpMehod for comp is "/comp/*" not "/comp/*/*"

Answer 1

Had the same problem. Adding * didn't work for individual endpoints. Try adding your {resource_path} and specify the {http_method}. Worked for me.

eg:

ResourcePath: '/api/resource/{Id}'
HttpMethod: 'GET'
