:(
Just signed up on Coinos myself. Attaching for payments works fine but when I attach it for receives, I get this error:
failed to create test invoice: failed to connect to wss://relay.coinos.io: null
which doesn't make sense since I can connect fine to it on the client. So sounds like something is wrong on our side.
To confirm: you get Cannot read properties of undefined (reading 'includes') no matter if you try to attach for sending or receiving, right?
