OAS validate returns error but no indication it's source.

[ChildishhAlbino]

Running oas validate ./swagger.yaml returns an error (which is expected). However, it does not give any indication of which file and what line that file is causing the error.

This has caused a massive headache of having to scour over lines of code to find very small indentation errors with almost no idea of where they are coming from.

Is this a possible feature to be added?

You have an example of the output that you received from an error state?

The lines causing the error were nowhere near line 26, column 29.

It would be nice if the error was more like
