Swagger..Unable to render this definition The provided definition does not specify a valid version field

Unable to render this definition The provided definition does not specify a valid version field.

Please indicate a valid Swagger or OpenAPI version field. Supported version fields are swagger: “2.0” and those that match openapi: 3.0.n (for example, openapi: 3.0.0).

Where do I need to insert the correct version to the stop the error below. Swagger editor works ok, but when launching a particular project I receive this error.First time using Swagger. Many Thanks

Answer

Your API definition is missing the OpenAPI/Swagger version number, in this case "swagger": "2.0". Add it at the beginning, like so:

{
    "swagger": "2.0",

    "title" : "Music API Documentation",
    ...
