NODE-4492 Description
What problem are you facing?
What driver and relevant dependency versions are you using?
Steps to reproduce?
when using promise.all I sometimes get error such as:
"MongoServerError: Given transaction number 5 does not match any in-progress transactions. The active transaction number is 4"
{
ok: 0,
code: 251,
codeName: 'NoSuchTransaction',
'$clusterTime': {
clusterTime: new Timestamp(
{ t: 1659288270, i: 1 }
)},
operationTime: new Timestamp(
{ t: 1659288270, i: 1 }
),
[Symbol(errorLabels)]: Set(1)
{ 'TransientTransactionError' }
}
code example:
the logic is inside main function and I use setInterval to check how many times I get the error and it seems like more than 50% of the time I get such error.
async function main(separateFirstCall) {
const clientConnection = await client.connect();
const db = await client.db(dbName);
const collection = await db.collection('transaction-test');
const session = clientConnection.startSession()
const options = {
readPreference: 'primary',
readConcern: { level: 'local' },
writeConcern: { w: 'majority' },
}
const names = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l']
await session.withTransaction(async () => {
await Promise.all(names.map(async name => {
try {
await collection.findOne({ name }, { session })
}
catch (e) {
console.log(e)
}
}))
}, options)
return 'done'} setInterval(() => {
main()
.then(console.log)
.catch(console.error)
.finally(() => client.close());
}, 5000)
