Fatal Exception when trying to resolve external path reference

[Jean-Daniel]

I'm not sure why it crash, but when trying to render the attached spec (bug.yml), I have the following exception:

[Error] TypeError: null is not an object (evaluating 'r._pointer=n')
	i (redoc.min.js:48:21834)
	o (redoc.min.js:48:21972)
	promiseReactionJob

Note that this spec render without issue in swagger editor (I didn't try swagger UI though).

I tried to pinpoint the issue and it look likes this is because the 2 paths references contains the same reference to the response array items schema. I didn't get further.

For the record (this files are in the attached zip):
