I'm submitting a (check one): [x] Bug report [ ] Feature request [ ] Regression (something that used to work, but stopped working in a newer version) [ ] Support request [ ] Documentation issue or request

Prerequisites

Current behavior

When providing a JSON schema which contains the schema version "$schema": "http://json-schema.org/draft-04/schema#" no form is generated. Error message: Error: no schema with key or ref "http://json-schema.org/draft-06/schema#"

• Error is thrown by ajv.js

Expected behavior

• The schema is converted to supported draft06 and the form is generated.
• When internaly converting to draft06 of JSON schema the $schema property is updated (or removed if not possible)

IMPORTANT: How can we reproduce your problem?

1. open the demo app
2. paste example JSON schema:

   {
   "$schema": "http://json-schema.org/draft-04/schema#",
   "type": "object",
   "properties": {
       "Name": {
           "type": "string"
       }
   }
   }

   ->error is thrown no form is generated. Delete line "$schema": "http://json-schema.org/draft-04/schema#", -> form is generated

Environment

OS name & version: Win 10 Browser name & version: Firefox 58, Chrome 63 Angular version: see Demoapp, found in project using Angular 5.2.2 Angular JSON Schema Form version(s): see Demoapp, found in project using 0.7.0-alpha.1 Other relevant software or packages:

Any other relevant information

As workaround: delete the schema property before passing it on to JSON Schema Form.

any help would be appreciated, Failing with following error: ERROR Error: no schema with key or ref "http://json-schema.org/draft-06/schema#"

Is this library even compatible with JSON Schema draft 4?

Any news on this issue?

With the upper workaround it works for my generated schemas.
