OAS: An invalid HAR Request is produced when path item object contains properties other than http methods

[ostridm]

Description

Converting of some specifications to HAR results in having an invalid HAR Request, when path item object has parameters or servers properties specified.

Proposed solution

Filter out all the properties other than http methods according to the specification

Steps to reproduce

Pass the my-schema.yaml (see below) to the oas2har as follows:

import { oas2har } from '@har-sdk/oas';
import { readFile } from 'fs';
import { promisify } from 'util';
import { load } from 'js-yaml';

const content = await promisify(readFile)(
  './my-schema.yaml',
  'utf8'
);

const result = oas2har(load(content) as OpenAPIV2.Document);

Actual result
