oneOf returns unwanted errors about ajv HOT 1 CLOSED

I am still getting to grips with all the details of AJV but I do know that oneOf is one of (no pun intended) the most misunderstood and misused features of AJV. The most common advice I hear when dealing with oneOf is that you probably want to actually use anyOf. If the types in your oneOf have no overlap, then I think it's equivalent, but more efficient since it doesn't need to check ALL of the different types when it finds a match.

As for the error reporting I think that what you want may have once been the behaviour according to this response by EP so I can only assume it was changed to report all of the schemas that didn't match for good reasons.

So AFAIK this is not something that we'll be open to changing.
