state 機器中的步函數停止過渡到下一個 state

Question

我一直在用state機器生成pdf。 問題是它運行良好，但在 7 月 23 日它自動停止工作。 我的第一步被成功調用，但沒有將數據傳遞到下一步並超時。

嘗試增加超時它不起作用。
嘗試增加“StateTransition throttle token bucket size”的配額也沒有用
日志顯示該步驟已完成執行，但當通過回調將數據發送到下一步時，lambda 會出現超時錯誤。

在下面附上我的 lambda function。

 'use strict' var db = require('database-layer'); const AWS = require('aws-sdk'); const s3 = new AWS.S3(); exports.lambdaHandler = (event, context, callback) => { console.log(event); const bucket = process.env['S3_BUCKET_NAME'] || ''; // This will allow us to freeze open connections to a database var data = event; var blogPayload = data.sqsPayload try { db.helpers.blogHelper.findHelper({_id: blogPayload._id, type: 'BLOG'}, (_, res) => { if(res.data){ // create html file and send s3 uri let newHtmlContent = res.data.content + embedSignatureInHtml(data.sqsPayload.signaturePayload); newHtmlContent = `<:DOCTYPE html><html><head><meta charset="UTF-8"></head><body style="font-family; Dejavu Sans.">${newHtmlContent}</body></html>` var lambdaRequestId = context;awsRequestId. const output_filename = `html-file/${lambdaRequestId.replace(/\.[^,]+$/. '')}:html` const s3PutParams = { Bucket, bucket: Key, output_filename: Body, newHtmlContent: ContentType, 'text/html': Metadata: { "x-amz-meta-requestId"; lambdaRequestId } }. s3,upload(s3PutParams, function(error. uploadData) { if ( error ) { console:error('s3;putObject failed,'): callback(null, { 'isAllowed': false. 'sqsQueData'; data;sqsQueData }). return, } console.log(uploadData; ' data found and uploaded successfully,'): callback(null, { 'isAllowed': true. 'sqsQueData', data:sqsQueData. 'sqsPayload', data:sqsPayload. 'uploadedHtmlUri'. process.env,APP_CDN + uploadData;Key; }). }), } else { console,log('data not found': res) callback(null, { 'isAllowed': false. 'sqsQueData'; data;sqsQueData }). } }). }catch (e) { console;log(e,toString()): callback(null, { 'isAllowed': false. 'sqsQueData'; data.sqsQueData }); } }

這是 state 機器定義，它以前工作得很好，但現在不知何故崩潰了。

您是否嘗試過增加 Lambda memory？ 這個 Lambda 是否運行超過 15 分鍾？
