Using dereference with base url throws errors.

[telion2]

Hello,
My Schemas look like this:
Schema1:

{    //Schema stuff...
    "$ref": "./meta_nlp_schema.json#meta"
    ...
}

Schema2: (meta)

{...
      "$id": "/meta",
     ...
}

Say I use dereference without base url would lead to this error:
Error parsingSyntaxError: Invalid $ref pointer "meta". Pointers must begin with "#/"
Which is not a very helpful Error message, since belive my $ref to be correct following this guide:
https://swagger.io/docs/specification/using-ref/
Also mentioned in #42
I also tested it with these, which either threw a path error or just wrote the ref element without inserting the content:

 "$ref": "#/meta_nlp_schema.json#meta"
 "$ref": "#./meta_nlp_schema.json#meta"
 "$ref": "#meta_nlp_schema.json#meta"
 "$ref": "meta_nlp_schema.json#meta"
 "$ref": "#meta"
 "$ref": "#/meta"

Say I use a dereference with a base url (following #20):
jsonschema = await parser.dereference('./json_schemes/','./json_schemes/standard_message_schema.json', {});
Would lead to this Error:

 Error: Error opening file "C:\Medieninformaitk\Medieninformatik\BA\Code\ConChat\json_schemes\"
EISDIR: illegal operation on a directory, read
    at fs.readFile (C:\Medieninformaitk\Medieninformatik\BA\Code\ConChat\node_modules\json-schema-ref-parser\lib\resolvers\file.js:51:20)
    at FSReqWrap.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:37:12)

If I understand this error correctly, then $RefParser trys to read a folder, which of course doesnt work. But that is not the behavior I expected. I expected the Parser to resolve refs like above, relative to the folder I give as a base url.

Or to generalize my problem:
I want to parse a folder full of json schemas so I can validate them against a json object in js.
Can I do that here?

The error message you're getting:

Invalid $ref pointer "meta". Pointers must begin with "#/"

is caused by the missing / character in the JSON reference path.

"$ref": "./meta_nlp_schema.json#meta"

Add the missing / character after the # to resolve the error:

"$ref": "./meta_nlp_schema.json#/meta"
