Autorest error - swagger.json' is not a valid OpenAPI 2.0 definition (expected 'swagger: 2.0')

Question

My api is running net core 3.0 with Swashbuckle.AspNetCore 5.0.0-rc5

When I run autorest on my generated swagger.json file I get:

swagger.json is not         


        

Answer 1

Followed this thread, auto rest doesn’t support latest open api yet but there are workarounds

https://github.com/Azure/autorest/issues/2680

You can do this:

app.UseSwagger(o => o.SerializeAsV2 = true);
