Connecting from browser to dGraph wss

[gotjoshua]

i am trying to use the observable recipe with a dgraph GraphQL backend.

Interestingly enough, i can connect to a subscription query via GraphQL Playground
but not from my localhost app in the browser.

Actually, polling will be performant enough for my current use case, but I want to know how to set up wss with server push, for future reference...

browser

GraphQL Playground

the error doesn't tell me much...

any help?

Probably because Dgraph still does not support graphql-ws. GraphQL playground still uses the legacy subscription-transport-ws which is why you can connect using it.

Made an issue at Dgraph's Discuss a while ago.
