I'm starting Javascript and async programming and I'm stuck with this problem.
I want to collect data from a collection in MongoDB database and schedule/start a cron job with this data.
const startCronJobs = (addressesArray) => {
for (idx in addressesArray) {
cron.schedule(('* * * * * ', () => {
console.log(addressesArray[idx]);
})).start();
}
}
const handleConnectedWallets = async () => {
const docs = await walletModel.find({}); // Retrieve all docs in the collection
return (docs.map((doc) => { return doc.address }))
}
handleConnectedWallets().then((res) => {
startCronJobs(res) // If console.log(res) -> ['0x06t...gq', '0x08as...af']
})
And i don't understand why I have the following error:
node:internal/process/promises:246
triggerUncaughtException(err, true /* fromPromise */);
^
[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "execution must be a function".] {
code: 'ERR_UNHANDLED_REJECTION'
}
I obviously tried to catch and throw the error after the then() but got the same error.
I must miss something!
Thanks for your help
You have a pair of parens too many. console.log((x, y)) would only log y.
cron.schedule('* * * * * ', () => {
console.log(addressesArray[idx]);
}).start();
