Day 18: API Specification - Expected response to be object but found array instead

Ask the Experts and Postman Tips

Hey, though there is an existing question on this topic, I didn’t quite understand it. I have tried all sorts of methods, to no avail.

To the question, in the schemas I defined the /cosmos request as in the image below but I am still getting this issue of expecting an object but found array instead.

The Error:

The Request and Response:

image718×487 12.8 KB

This is my schema definition for the request…

I tried changing the example to fit the response type but upon validating, Postman throws an error of unexpected change in the example.

@kevinc-postman Any idea here?

Hi,

I’m really new to schemas but after playing around, if you change it from this;

components:
  schemas:
    Cosmos:
      type: array
      required:
        - id
        - name
      properties:
        id:
          type: integer
          format: int64
        name:
          type: string
        tag:
          type: string

To this (adding in the “items:” for array and indenting everything underneath;

components:
  schemas:
    Cosmos:
      type: array
      items:
        required:
            - id
            - name
        properties:
            id:
            type: integer
            format: int64
            name:
            type: string
            tag:
            type: string

And then refresh the page (I was using Postman in the browser)… then that warning message disappears.

Not sure if this is the legitimate fix for the issue though?

Hey @w4dd325 , thank you so much! I tried this but it still threw the error. I re-forked the collection and did it again and it works… don’t really know what went wrong in the old one.

It’s been intermittent for me too. I’ve just had it working, then throws a warning, then it worked again.
Quite strange.

Yeah, it was very strange. Honestly, was losing my mind over this. Glad to know I’m not the only one lol.
