userId is Int when GET, but String when get result after POST

[elijah-rappaport]

There is a discrepancy in the type for userId. This appears to be an issue on all the endpoints. Below is an illustration of the issue on the "posts" endpoint.

When I GET a post, userId is an Int, as you see here...

GET 'https://jsonplaceholder.typicode.com/posts/1' curl "https://jsonplaceholder.typicode.com/posts/1" 200 'https://jsonplaceholder.typicode.com/posts/1' { "userId": 1, <==== Int "id": 1, "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit", "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto" }

When I get the result after POST a new post, userId is a String, as you see here...

POST 'https://jsonplaceholder.typicode.com/posts' Content-Type : application/x-www-form-urlencoded HttpBody : body=B&title=A&userId=1&id=-1 curl "https://jsonplaceholder.typicode.com/posts"
-X POST
-H 'Content-Type: application/x-www-form-urlencoded'
-d 'body=B&title=A&userId=1&id=-1' 201 'https://jsonplaceholder.typicode.com/posts' { "body": "B", "title": "A", "userId": "1", <==== String "id": 101 }

This issue causes errors in my code when trying to decode or encode using the same struct struct Post: Codable { let id: Int? let userId: Int <== this will cause error when trying to convert the json received back from a POST, as I'm expecting an Int but getting a String var title: String var body: String }
