Question

I get so confused by how the `graphql` works Here is my operations First I try `prefect server config gt origin yml` then launch it with docker compose App works on `localhost 8080` Under `getting started` tab I put `` as graphql end point and it works So far so good Then I try `prefect server config graphql port 40002 gt my prefect yml` launch with docker composer App still works on the same address However I tried to give ui the graphql endpoint with values ` ` with without last ` ` None of them works I try in browser `` it gives me a console to play As long as I touched graphql port I will not be able to set up a workable local sever Really appreciate if someone can help me take a look

Hi < Enda Peng> the problem here is that the UI doesn t need the GraphQL port it needs the Apollo port Apollo is a service that sits in front of GraphQL and is the main entry point for external clients

So in what you ve linked the Apollo is still at port 4200 and GraphQL is at 40002 instead of 4201

It doesn t work for me I tried twice first time I don t touch anything ``` GRAPHQL SERVICE HOST GRAPHQL SERVICE PORT 4201 HASURA API URL PREFECT API HEALTH URL PREFECT API URL PREFECT SERVER TELEMETRY ENABLED true ``` I put `` on the webpage it doesn t work Then I think the second line look suspicious So I use ``` GRAPHQL SERVICE HOST GRAPHQL SERVICE PORT 40002 HASURA API URL PREFECT API HEALTH URL PREFECT API URL PREFECT SERVER TELEMETRY ENABLED true ``` Also `` doesn t work on web app
