I want to import OpenAPI 3.0 Specs from my Swagger.
But it shows “Error while fetching data from link”, although any web browser and CURL can access the data accordingly.
I run an REST-API built with NestJS, and the Swagger Docs as JSON can be fetched via the URL:
http://localhost:3000/swagger/json
But when I click on “import” and paste this URL, it shows the error message mentioned above.
Is there any other way to import a Swagger API?
