License object URL is not a proper URL

Issue ID: v3-warning-license-url

Description

The URL defined in the url field of the license object is not a proper URL.

The license object itself and the url field in it are optional. If you do not defined either, your OpenAPI definition is still a valid contract. However, if you do reference your license location, the OpenAPI Specification (OAS) requires that all URLs in the API contract must be proper URLs in a valid format.

For more details, see the OpenAPI Specification

Example

The following is an example of how this issue could look in your API definition. In this case, the URL is missing the protocol prefix and has an extra space:

{
    "license" : {
        "name": "Apache 2.0",
        "url": "www.apache.org/licenses/ LICENSE-2.0.html"
    }
}

Remediation

Make sure that all URLs in your API are proper URLs and have a valid format.

{
    "license" : {
        "name": "Apache 2.0",
        "url": "www.apache.org/licenses/LICENSE-2.0.html"
    }
}
