Last encoding failure

[brycefernandes]

Hi , I'm stuck at a place. I've tried looking for examples specific to js but no luck
Here is the code.
`const nats = require("nats");
const { encode, decode } = require("nats-jwt");

class AuthService {
constructor(issuerKeyPair, handler) {
this.issuerKeyPair = issuerKeyPair;
this.handler = handler;
}

async handle(request) {
try {
console.log("AuthService: Handling request", request.data.toString());
const rc = decode(request.data.toString());
if (!rc) {
throw new Error("Invalid authorization request");
}
console.log("AuthService: Decoded request:", JSON.stringify(rc, null, 2));

  const claims = {
    sub: rc.sub,
    aud: "CHAT",
  };

  console.log("AuthService: Calling handler...");
  const handledClaims = await this.handler(rc);
  Object.assign(claims, handledClaims);

  console.log("AuthService: Validating and signing claims...");
  const token = await this.validateAndSign(claims);
  console.log("AuthService: Responding to request...");
  this.respond(request, rc.sub, rc.nats.server_id.id, token);
} catch (err) {
  console.error("AuthService: Error handling auth request", err);
  request.respond(nats.Empty, { status: 500 });
}

}

respond(request, userNKey, serverId, userJWT) {
console.log("AuthService: Constructing response...");
const rc = {
sub: userNKey,
aud: serverId,
jwt: userJWT,
};

console.log("AuthService: Signing response...");
const token = encode(rc, this.issuerKeyPair);
console.log("AuthService: Sending response...");
request.respond(Buffer.from(token));

}

async validateAndSign(claims) {
console.log(
"AuthService: Validating and signing claims:",
JSON.stringify(claims, null, 2),
);
return encode(claims, this.issuerKeyPair);
}
}

module.exports = AuthService;
`

I get an error on this line
return encode(claims, this.issuerKeyPair);

What are we supposed to do here? I'm sure there is a method, but I can figure it out.

Are you trying to implement a call out?

[aricart]

If you are trying to implement a callout, perhaps take a look at this (in particular the tests).
https://github.com/synadia-io/orbit.js/tree/authcallout/callout

Note that the above branch is a WIP, so things will change.

As for your description above, it would be very helpful to explain what you are trying to do and the exact error you are getting.
