JSON schema Draft hint not being respected

[bloche]

Overview

When using JSON schema in RAML types the $schema property doesn't appear to be respected. Back in JSON schema Draft 4 the exclusiveMaximum property was a boolean, it was updated to be an integer in later draft revisions (see: https://json-schema.org/understanding-json-schema/reference/numeric.html#range). However when I run the webapi-parser's validate function on my RAML I get an error that says exclusiveMaximum should be of type boolean, not integer.

                  "type": "integer",
                  "exclusiveMaximum": 10
                }
              }
            example: [1, 2, 3, 4, 5]
`;

const validate = async (raml) => {
  const model = await wap.raml10.parse(raml);
  const report = await wap.raml10.validate(model);

  console.log(report.conforms ? 'Valid' : 'Invalid');
  // output errors
  report.results.forEach(r => {
    const pos = `(line: ${r.position.start.line}, column: ${r.position.start.column})`;
    console.log(`${pos} [${r.level}]`);
    console.log(r.message);
  });
}

validate(raml).then(e => e).catch(e => console.error(e));

When I run this I get:

Invalid
(line: 20, column: 41) [Violation]
Expecting !!bool and !!int provided

Question

Is this a bug with the parser, or is there a way I can force the parser to either respect the $schema property or specify what draft I want it to validate with?

Hi @bloche.

It's a limitation of our dependency lib AMF. I've created a gh issue and requested more drafts to be supported.

I'll let you know when we release a new version of webapi-parser with newer json schema versions supported.

Thanks @postatum

Hi @bloche.

Looks like our dependency lib now supports JSON Schemas up to draft 7. We are currently working on updating our lib as well. I'll let you know when the new version is available.

@postatum That's great to hear, thanks for keeping me informed.
