Path parameter must have the property 'required' set to 'true'

Description

The required property of the path parameter in question is either missing altogether, or it is set to false. All path parameters must have the property required set to true.

For more details, see the OpenAPI Specification.

Example

The following is an example of how this issue could look in your API definition. Here, the property required is set to false:

{
  "name": "ID",
  "in": "path",
  "description": "ID to fetch",
  "required": false,
  "type": "integer"
...
}

While here, the property has been forgotten altogether:

{
  "name": "ID",
  "in": "path",
  "description": "ID to fetch",
  "type": "integer"
...
}

Remediation

Make sure that all path parameters have the required property set to true.

{
  "name": "ID",
  "in": "path",
  "description": "ID to fetch",
  "required": true,
  "type": "integer"
...
}
