Hey,
I have followed all the steps in Implement a custom web service that uses anonymous authentication | Creatio Academy
Note: Using Local Creatio Env, Creation:Energy 8.2v
`UsrAnonymousConfigurationService` File
Error: Internal Server Error
Like
Hello,
Please recreate the error and check both the Error.log file in the application logs (located at C:\Windows\Temp\Creatio by default) and the Windows events viewer logs to see the actual error message. This can be returned in case the services.config file was setup incorrectly or because of the incorrect setup in the Terrasoft.WebApp/Web.config file.
There might be an issue in the web.config file at the following line: `<add key="AllowedLocations" value="[Previous values];ServiceModel/UsrAnonymousConfigurationService.svc" />`.
I’m not sure what values should replace [Previous values].
Hello!
This issue might occur due to not enough setup in web.config on how to set it you can read here - https://academy.creatio.com/docs/8.x/dev/development-on-creatio-platform/back-end-development/web-services/web-service-implementation/examples/web-service-anonymous-authentication#title-2145-4
