This is not a valid API definition.

Each path must be listed only once, and all HTTP methods applicable to that path must be listed under that path, as follows:

paths:
  /user:
    post:
      ...
    delete:
       ...

There is a problem with duplicate mapping keys Why?

[hkosova]

@gi-hu-se You can't have two get inside a path (or, in general, multiple instances of the same HTTP method). If you are designing a new API, split this path into two different paths, each with its own get.

Here's a related feature request in the OpenAPI Specification repository:
OAI/OpenAPI-Specification#182
