requests to /foo/bar to an API Gateway (v1) resource of /foo/{proxy+} return 404 as they are routed to /bar

[eran-medan]

I'm having the same issue as in this comment #454 (comment) (should be probably reopened?)

Upgraded from the legacy aws-serverless-express and for some reason it takes the path from pathParameters.proxy (which is bar) and not the request.path (which is /foo/bar)

I'll be happy to work on a PR if you indeed confirm it's a bug

Offending line is https://github.com/vendia/serverless-express/blob/0909ec4ffd09d9fd22538257b721b7d076d03732/src/event-sources/utils.js#LL7C21-L7C21

A quick workaround is to change the name of the greedy path variable in API Gateway e.g. rename {proxy+} to {route+}.

Facing the same issue as well. My team wasn't keen on messing with the greedy path variable names since that would entail a relatively uncomfortable change in API Gateway. Our routes are well established and running well.

Another quick workaround is to delete event.pathParameters.proxy if it exists and pass the edited event into serverlessExpress. This way util.js is forced to use event.path.

To add to @mohammedsahl comment - vendia v4 does not seem to be compatible with how AWS Amplify sets up REST endpoints in API Gateway (https://docs.amplify.aws/cli/restapi/restapi/#create-a-rest-api). Since AWS Amplify allows for varying auth levels per endpoint, and the auth checks are done by API Gateway, it uses /foo/{proxy+} rather than /{proxy+}.

To make this lib work with amplify, you have to do what @mohammedsahl describes in #648 (comment) or similar.

Can you try the v5 branch #649? We'll merge this after additional verification

[mohammedsahl]

Hey @brett-vendia. Unfortunately, it still doesn't seem to work. This event.multiValueQueryStringParameters in our event is null and so the params passed to to url.format() are { pathname: '/<somePathParamter>', query: null }

If it helps our event has the following structure

{
  "resource": "/foo/{proxy+}",
  "path": "/foo/<PathParamter>",
  ...
  "queryStringParameters": null,
  "multiValueQueryStringParameters": null,
  "pathParameters": {
    "proxy": "<PathParamter>"
  },
  ...
}
