Callback reference imaginary error with OpenAPI 3.1

[mdaneri]

this is a sample OpenAPI document if I set openapi 3.1.0 I get the following error Line 35 Callback Object values must be of Path Item Object shape

If I switch back to 3.0.0 everything is fine. I checked the OpenAPI 3.1 and there are no changes regarding callback

openapi: 3.1.0

I need a fix for this :(

Edit: My mistake was that the callback url was not wrapped in {} brackets. When I added the brackets, the issue went away: {$request.body.callbackUrl}
