Attempting to validate a schema against a meta-schema errors out

[CodeGat]

Thanks for creating this action - it's been a huge help in a bunch of my projects.

Instead of validating data against a schema, I've been looking to validate a schema against a meta-schema (usually a JSON Standards schema such as http://json-schema.org/draft-07/schema#), but I can't seem to get it to work.

Attempts

Attempting with:

with:
  file: schema.json
  json_schema: meta-schema.json  # `curl` http://json-schema.org/draft-07/schema# into `meta-schema.json`
  # No json_schema_version

fails with:

Error: schema with key or id "http://json-schema.org/draft-07/schema" already exists

Whereas something like:

with:
  file: schema.json
  json_schema_version: '07-draft'

Doesn't pick up on obvious error with schema.json.

Any help would be appreciated :)
