Hey,
Currently trying to implement a custom session storage using MySQL.
After I add the app it throws a missing access token when creating graphQL client
InternalServerError: Missing access token when creating GraphQL client
Here is my custom session code
import { Session} from '@shopify/shopify-api/dist/auth/session'
const mysql = require('mysql');
const connection = mysql.createConnection({
host:'[host]',
user:'[user]',
password:'[password]',
database:'[database]'
})
console.log('is connecting')
connection.connect();
let domain_id = '';
export async function storeCallback(session){
try{
console.log("calls storeCallback")
let data = session;
console.log("data " +JSON.stringify(data))
data.onlineAccessInfo = JSON.stringify(session.onlineAccessInfo)
if(data.id.indexOf(`${data.shop}`)> -1){
console.log("data.id got called")
domain_id = data.id
}
let connectionQuery = new Promise((resolve, reject) =>{
connection.query(`INSERT INTO shop (shop_url, session_id, domain_id, access_token, state, isOnline, onlineAccessinfo, scope) VALUES ('${data.shop}','${data.id}','${domain_id}','${data.accessToken}','${data.state}','${data.isOnline}','${data.onlineAccessInfo}','${data.scope}') ON DUPLICATE KEY UPDATE access_token='${data.accessToken}', state='${data.state}', session_id='${data.id}',domain_id='${domain_id}',scope='${data.scope}',onlineAccessInfo='${data.onlineAccessInfo}'`,
function(error, results, fields){
if(error) throw error;
resolve();
}
);
});
await connectionQuery
return true;
}catch(e){
console.log("got this error")
throw new Error(e);
}
}
export async function loadCallback(id){
try{
let session = new Session(id);
let query = new Promise((resolve, reject) =>{
connection.query(`SELECT * FROM shop WHERE session_id ='${id}' OR domain_id='${id}' LIMIT 1`,
function(error, results, fields){
if (error) throw error;
session.shop = results[0].shop_url;
session.state = results[0].state;
session.scope = results[0].scope;
session.isOnline = results[0].isOnline == 'true' ? true:false;
session.onlineAccessInfo = results[0].onlineAccessInfo;
session.accessToken = results[0].accessToken;
const date = new Date();
date.setDate(date.getDate() + 1);
session.expires = date;
if(session.expires && typeof session.exipres === 'string'){
session.expires = new Date(session.expires);
}
resolve();
}
);
});
await query;
return session;
}catch(err){
throw new Error(err)
}
}
export async function deleteCallback(id){
try{
return false;
}catch(e){
throw new Error(e)
}
}
And here is my server.js

const ACTIVE_SHOPIFY_SHOPS = {};
app.prepare().then(async () => {

server.use(

);
const handleRequest = async (ctx) => {

}
);
router.get("(/_next/static/.*)", handleRequest); // Static content is clear
router.get("/_next/webpack-hmr", handleRequest); // Webpack content is clear

router.get("(.*)", async (ctx) => {
const shop = ctx.query.shop;
console.log("get request "+ shop)
// This shop hasn't been seen yet, go through OAuth to create a session
if (ACTIVE_SHOPIFY_SHOPS[shop] === undefined) {
console.log("its getting redirected")
ctx.redirect(`/auth?shop=${shop}`);
} else {
await handleRequest(ctx);
}
});
server.use(router.allowedMethods());
server.use(router.routes());
server.listen(port, () => {
console.log(`> Ready on http://localhost:${port}`);
});
});
What am I missing?
