Hi,

I have the following entry in my serverless.yml

```
handler: src/handlers/users.getById
name: SKUsersGetById
events:
  - http:
      path: users/{id}
      method: get
      request:
        parameters:
          paths:
            id: true
      cors: true

```

It is not generating the path parameters in the Cloudformation file. So the AWS SDK is not generated correctly and no params are included in the generated sdk.

Am I doing something wrong or is this a bug in serverless?

Thanks for your help!

I’ve never tried to define the variables in the `path` and `request` properties at the same time (although I can see where you got the example from in the docs).

Try this definition:

```auto
handler: src/handlers/users.getById
name: SKUsersGetById
events:
  - http:
      path: users/{id}
      method: get
      cors: true

```

You’ll still see the `id` variable in the `event.pathParameters` object (i.e. `event.pathParameters.id`).

Hi,

tanks for your answer.  
I have done this before.  
The lambda functions are working this way but AWS then doesn’t have the path parameters in the generated SDK.

Sorry, I don’t understand what you mean by “generated SDK”.

If you go to `/users/test` do you see the value “test” in the `event.pathParameters.id` property? If so, then path parameter is being mapped to the variable defined.

I mean the API Gateway Client SDK Generation on AWS after you deploy your API.

Ah, now I understand.

I’ve never used that myself, so I’m not sure what’s missing to connect your `serverless.yml` function definition and the SDK definition.

Hi @gkTim, this might help:

I’ve been looking ages for this. Thank you. (Sorry to revive this old post, but after 2 years this problem still exist)

Hey that’s awesome … that’s why I posted it. 🙂 Yeah I don’t know how many people are using the Generated SDK in this crowd.
