Error for following JSON Schema, issue with the use of $async

[theisuru]

This is generic JSON Schema used in IDEA for validating JSON Schema itself. But if I try to validate any JSON using this Schema validator gives and error saying async schema referenced by sync schema. I suppose this is a problem with usage of $async in the library. Please see the Schema below.

Hi @theisuru,

Thanks for your comment. We are going to look into this issue and let you know what we found.

[ke4]

And the solution is:

You just have to insert "$id": "<WHATEVER_ID_YOU_WOULD_LIKE_TO_HAVE>" after $schema field and the validation should work. At least it works for me. ;-)

Please, let me know if you still have any problem.

Many thanks,

Karoly
