Header property is not applicable to the header's type

Description

A property defined for a header is not applicable to the type of the header.

For more details, see the OpenAPI Specification.

Example

The following is an example of how this issue could look in your API definition. The rate limiting header can include parameters of the type integer, but the parameters also have the property maxLength defined which is a property of string parameters, not integers:

{
 "headers": {
    "X-Rate-Limit-Limit": {
      "description": "The number of requests allowed in the current period",
      "type": "integer",
      "maxLength": 8,
    },
    ...
  }
}

Remediation

Make sure that all properties defined for headers match the header type.

{
 "headers": {
    "X-Rate-Limit-Limit": {
      "description": "The number of requests allowed in the current period",
      "type": "integer"
    },
    ...
  }
}
