Describe the bug you're encountering

Validation error of OpenApi schema - within an OperationObject, a ParametersObject doesn't accept in: path as a valid location

To reproduce...

1. Paste the above YAML into the editor on editor.swagger.io
2. Read the Errors on the right side

Expected behavior

No validation Errors and for "path" to be an acceptable "in" location

The errors are misleading. The real issue is that the path parameter is missing required: true.

Also, allowEmptyValue only applies to query parameters but not path patameters.

Keeping this around as a validation enhancement - the messaging here isn't great.

As is with most of these issues, the problem lies in the JSON Schema validator not being smart enough to make guesses about which anyOf a user intended, and instead complaining about not matching the anyOf itself... which is not useful.

I've opened a pull request (#1985) that will close this issue.

Here's what Swagger Editor reports with my changes:

Structural error at […]get.parameters.0
should have required property 'required'
missingProperty: required
