Tengo una API de back-end de nodejs/express que cuando recibo cientos de solicitudes en segundos empiezo a obtener resultados mixtos donde los datos se cruzan entre las solicitudes y conducen a resultados inesperados e incorrectos. ¿Puede alguien señalarme dónde estoy definiendo incorrectamente las variables que cuando obtengo una de las funciones de espera hace que las otras variables se sobrescriban con los siguientes datos de solicitudes y causen mis problemas?

 router.post('/autoscan3', async(req,res,next) => { let authrule = "autoscan" console.log(req.body.companyDomain + " " + req.body.user + " for folder: " + req.body.folderid) let totalscans = 0; let client = await getDB(); let authorizationResults = await checkAuthorization(client, req.body.companyDomain); const featureSet = authorizationResults.features; let company = authorizationResults.company; const clientid = authorizationResults.client_id; const clientsecret = authorizationResults.secret; let tenantid = await getTenantID(req.body.companyDomain, client); let token = await msgraphservices.getClientCredentialsAccessToken(tenantid, clientid, clientsecret) let scanResults = [] let folderscans = 0; try{ for(let a = 0; a < req.body.messages.length; a++){ let senderAddress = req.body.messages[a].senderAddress; let emailBody = req.body.messages[a].emailBody; let messageid = req.body.messages[a].messageid; let receivedDateTime = req.body.messages[a].receivedDateTime; let user = req.body.messages[a].recieverAddress; let subject = req.body.messages[a].subject; let attachments = req.body.messages[a].attachments; let links = req.body.messages[a].emailBodyLinks; let headers = req.body.messages[a].headers let knownaddress if (senderAddress.includes(req.body.companyDomain)) { knownaddress = 10 } else { knownaddress = await searchForSender(client, senderAddress, req.body.user, token, "");} let assessmentResults = await assessment( messageid, emailBody, senderAddress, user, subject, receivedDateTime, company, attachments, links, req.body.companyDomain, client, headers, knownaddress, featureSet, authrule ) console.log('adding to folderscans') folderscans++ try { await msgraphservices.updateUserCategory2(messageid, req.body.user, req.body.folderid, assessmentResults.riskFactor,token) } catch(e) { console.log(`error on category tag for ${messageid} with user ${req.body.user}`); console.log(e); } } console.log(`folder scans ${folderscans}`); totalscans = totalscans + folderscans return res.status(200).json({status:"success", totalscans:totalscans}); } catch(e) { console.log(`error while trying to loop for user ${req.body.user}`) console.log(e) logapierror(e.stack, req.body.user, req.body) return res.status(200).json({status:'error', totalscans:totalscans, error:e}); } });
