Problem with client side running using `yarn`

[dim1tri]

Hi, could anybody help me with the error I'm facing with the react app (hasura side works ok):

➜ yarn dev
yarn run v1.22.10
$ next dev

Hey Dimitri,

That error you're seeing is because the URL given to the GraphQL client in the React app for querying the API is relative. You can see it here:

https://github.com/hasura/data-dictionary/blob/9716babd31f4d747f728964c401a89124c95e698/react-app/utils/graphqlClient.ts#L3-L8

It shouldn't break anything though -- all of the queries should still succeed. Is the client not able to run queries for you?

It wants a full URL, which is more difficult to manage between environments than just using a relative URL to whatever the current host is. If anyone can PR a dynamic hostname resolution method that works for Next.js to fix this error (can't use window because half the time the code will run on Node) that would be great.

For now I just left the error/warning as it wasn't seeming to actually fail/cause any issues for me.
