Swagger support to Abp Elsa demo #1530

VivekKoppula created 3 years ago

I am trying to add swagger support by doing the following.

Added the following line of code the web module.

context.Services.AddElsaApiEndpoints(); // The following is throwing exception context.Services.AddElsaSwagger();

But it is throwing exception. The exception is shown below for your reference. So I had to comment out.

Also tried to add the following code in the same ElsaDemoWebModule.cs file.

app.UseAbpSwaggerUI(options => { options.SwaggerEndpoint("/swagger/v1/swagger.json", "ElsaDemo API"); // The following did not help. options.SwaggerEndpoint("/swagger/v1/swagger.json", "Elsa"); });

But it did help. I get Elsa in the drop down, but selecting it does not give the elsa swagger UI.

The full exception is as follows.

An unhandled exception occurred while processing the request. ArgumentException: An item with the same key has already been added. Key: v1 System.Collections.Generic.Dictionary<TKey, TValue>.TryInsert(TKey key, TValue value, InsertionBehavior behavior)
