Graphql is missing or what?

[dongalor]

Hello, guys!
Trying to set up this explorer. Application runs but when I open it in browser loaders appear, but nothing happens. In logs I can see, that it can't access graphql server. Do I need to set it up separately or it's supposed that we need to use bitquery's graphql (found it in Dockerfile env variables).

Thank you for you help in advance!
