Swagger index.html page not accessible through loadbalancer url after deployment

[DibyoChatterjee]

.Net Core 5.0 web api project with Swashbuckle.AspNetCore version 5.6.3.

ISSUE-:
Swagger index.html page or the Swagger json file not accessible after deployment to AWS with a Load balancer url.

STEPS TO REPRODUCE:

I am working in a team in which we have created a solution with multiple Web API projects. Each project has its own startup.cs file & the corresponding swagger configuration details.

Currently we are having two such web api projects -: masterService, userService.

In masterService api project, we have kept the swagger configuration as it is (i.e., in configureServices(), we have services.AddSwaggerGen(...) & in configure(), we have the app.UseSwagger(), app.UseSwaggerUI(options=> options.swaggerEndpoint('/swagger/v1/swagger.json', 'masterservice v1').

Now this Web API is build through Dockerfile & then Jenkins pipeline deploys it to AWS. In AWS we have loadbalancer.

EXPECTED RESULT:

Accessing the /swagger/index.html page using loadbalancer url (i.e, https://loadbalancerurl/swagger/index.html) should show the swagger index.html page with all API endpoints of masterService.

ACTUAL RESULT:

When requested through browser, 404 is returned.

##TRIED:##
I tried to modify the swagger url like /masterService/swagger/index.html (as we have multiple api projects) using routeTemplate(...), then routePefix but no luck. Then I reverted back to the old solution.

##Question:##
What is the issue here? Kindly help.

for .netcore you need another project: https://github.com/domaindrivendev/Swashbuckle.AspNetCore
