JSON schema validation fails when there is no internet connection

I am getting below error while trying to validate a JSON against a schema

 java.io.UncheckedIOException: java.net.UnknownHostException: json-schema.org
  at org.everit.json.schema.loader.internal.DefaultSchemaClient.get(DefaultSchemaClient.java:27)

The schema has a ref to “$ref”: “http://json-schema.org/draft-07/schema#” and this fails at DefaultSchemaClient.java:27 when there is no internet connection.

Is there a way to get around this issue ?

In which case, fair enough! I’d expect this to be done in addition to the meta-schema evaluation should it fail. I would guess using the meta-schema might be a quick first pass.

Having said that, I’m not sure that would be beneficial. I’m not sure my coffee has kicked in yet!

I would expect when a JSON Schema is provided, it’s validated against the appropriate meta-schema before being used.

The library throws informative exceptions in case the schema turns out to be un-processable. This is done programmatically using an internal API and the meta-schema is not used for this purpose (hence, the library doesn’t expect to be able to find anything at the dialect URI).
