Your API spec must include one of these fields at the root level : swagger: "2.0" or openapi: "3.0.0" or "3.1.0" If you’re using Swashbuckle in .NET , check your Startup.cs or Program.cs configuration: services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" }); }); confirm the top line has openapi: "3.0.1" or swagger: "2.0" .
