Incorrect error message

[tatomyr]

Describe the bug Sometimes we get the following error:

  - Cannot read properties of null (reading 'allOf').

However, it isn't clear where exactly to look. Moreover, there may be no allOf keyword in the definition at all.

To Reproduce See the conversation.

Expected behavior It should show a correct error message whatever it is.
