Describe the bug you’re encountering

This is a file I’m working on. When I still have not defined the schema for a path parameter, editor reports an error at the “in” property, claiming the allowed values are only “query, header, cookie”. This is very confusing and in fact wrong. If I just complete the parameter definition by providing it’s schema, this error is not reported, although the value for “in” is still “path”.

As a learner myself to the OpenAPI specification I was quite confused by the misleading error, and spent much time consulting with documents and examples, then finally concluded that it’s a false alarm.

Schema error at paths['/contact/{contactId}'].get.parameters[0].in
should be equal to one of the allowed values
allowedValues: query, header, cookie
Jump to line 43

Expected behavior

The error should not be reported in the first place. Or, if that’s not possible or difficult, at least make the message not so misleading.
