Hello!
I have a problem while doing a Creating a child case Challenge and I don’t know how to solve it. I checked with Challenge Walkthrought and it corresponded to what I did. I can’t figure out where the error is.
@StanislavaN If you go to the ‘Case types’ view on the left, do you see ‘Service’ listed and can you start that case by using ‘Save and run’? Did you also add the child case with App Studio and not Dev Studio? (App Studio automatically creates a child case with this automation, Dev Studio lets you choose a top or child case). I don’t have the issue with this module, it would be helpful if you had a video of your steps for this challenge just for a side-by-side comparison 
I too faced the same issue. This error is coming because you’ve not chosen a service provider. No service provider is available in the location that you provided in the earlier screen.
What I did to correct it was to choose a location (city, state) in the US in the previous screen.
If you do so, “select service provider” screen wont be blank. It will show available service providers in that area. Then you need to choose a service provider by clicking a button provided at the last column of any one of service provider.
I have attached the list of service providers used in this case, you may choose any of the city and state provided in the list.
