I am building an HTTP API in AWS Gateway, and I can't understand how to encode the path parameters.
The documentation says
API Gateway decodes URL-encoded request parameters before passing them to your backend integration.
But apparently there is more to it than that....
I have a route GET /{example}/thing, and I want to pass a/b as the parameter.
If I request /a/b/thing, I get 404 Not Found.
If I request /a%2Fb/thing, I get 404 Not Found.
If I request /a%25Fb/thing, I get 404 Not Found.
If I request /a%2525Fb/thing, I get 200 OK, but the Lambda function gets the parameter a%2Fb.
What encoding does API Gateway (HTTP API) use for its parameters?
How should encode the parameter a/b?
