grpc-js throws "unable to get issuer certificate" error while connecting about ln-service

[alexbosworth]

what are you specifying for the cert, can you share any code?

[saravanan7mani]

const {lnd} = lnService.authenticatedLndGrpc({
cert: "base64 of tls file downloaded from voltage",
macaroon: "base64 of admin.macaroon downloaded from voltage",
socket: "grpc endpoint uri of voltage node"
});

Please note, voltage's TLS cert file is actually CA provided.

[alexbosworth]

OK: try omitting the cert

[saravanan7mani]

Did that already. Received the below error.

OK I think this error comes from the server side so something is going on there, maybe you could ask voltageio for some advice?

Another thing to try is use an existing script like https://github.com/alexbosworth/balanceofsatoshis which uses ln-service: https://docs.voltage.cloud/balance-of-satoshis-guides/balance-of-satoshis - if that works then you could see how it is calling into the methods

[saravanan7mani]

Thanks. I will try those and update.

Removal of cert property worked.
