assignment to entry in nil map

[Joe]

Was working fine for the past week. Now cannot connect.

WSEndPoint to wss://rpc.polkadot.io/
Also tried with wss://service.elara.patract.io/Polkadot/xxxxxx (my own endpoint in elara)

WSEndPoint                = GetEnv("CHAIN_WS_ENDPOINT", "wss://rpc.polkadot.io/")
NetworkNode               = GetEnv("NETWORK_NODE", "polkadot")

Throws error:

[Joe]

related to the recent 0.9.11 release ?

[Joe]

if possible can someone share how to update the type registry to be compatible with the recent change?

@joshtharakan I think it’s a network connection problem, try to use other node point
