The root problem here is that User.changeset doesn’t require any fields, so sending it nils won’t cause it to be invalid.

HOWEVER

There are several other layers missing as well:

  • if there were validation errors, the code in the controller’s create function will make it fall-through and return {:error, changeset}. Do you have a fallback controller set up?

  • phoenix_swagger can help with this, but only if it’s correctly configured and enabled:

    • the name of the parameter create expects is user not body, the parameters block should start user(:body, Schema.ref(...)
    • the validations need to be wired up, either through the PhoenixSwagger.Plug.Validate plug or by directly calling PhoenixSwagger.ConnValidator.validate! directly.
