Session is Undefined after Creating Rest Client using a Session created from Storage

[nickheady]

I have a cloud function whose purpose is to get the shop's orders.

I create the shopify object:

require('@shopify/shopify-api/adapters/node');
var {shopifyApi, LATEST_API_VERSION, Session} = require('@shopify/shopify-api');

const shopify = shopifyApi({
    apiKey: 'XXXXXXX',
    apiSecretKey: 'XXXXXXXXXX',
    scopes: ['read_orders'],
    hostName: 'host-name.net'
});

Then I pull the session data from the database and create the rest client and make a call:

var sessionData = getSessionFromStorage();
const sessionCopy = new Session(sessionData);
const restClient = new shopify.clients.Rest({sessionCopy});

const getResponse = await restClient.get({
    path: 'orders',
});

But I get this error: TypeError: Cannot read properties of undefined (reading 'accessToken') From this line: (/node_modules/@shopify/shopify-api/dist/cjs/lib/clients/admin/rest/client.js:27:50) which is inside the rest client constructor, this if statement:

if (!config.isCustomStoreApp && !session.accessToken) {
       throw new error.MissingRequiredArgument('Missing access token when creating REST client');
}

So 'session' is undefined here. I cannot figure out why. sessionData is just an object with these properties:

accessToken
id
isOnline
scope
shop
state

After creating a new session with const sessionCopy = new Session(sessionData); the sessionCopy object contains the above plus:

expires: undefined
onlineAccessInfo: undefined

Hey @nickheady,

thanks for reporting this issue. Could it be that this line

const restClient = new shopify.clients.Rest({sessionCopy});

should instead be

const restClient = new shopify.clients.Rest({session: sessionCopy});
