Download large file aborted using axios nodejs in Confluence Cloud

marketUser September 19, 2022

Hello

■Background

In Google Cloud Run using AXIOS with node.js for file downloading from atlassian Confluence, when the file's size is greater than 100M,download failed.

■What I did

Read response data in chunks. I found that a request oborted exception occurred when it reached the end. The response data was not read completely. By the way my code can download successfully more than 100M from zoom.

■Code

↓source code↓

const writer = fs.createWriteStream(filepath);

const response = await Axios({

   url: fileUrl,

   method: "GET",

   responseType: "stream",

   validateStatus : null,

   httpAgent: new http.Agent({ keepAlive: true }),

   httpsAgent: new https.Agent({ keepAlive: true })

}).catch(err => {

   console.log("axios error: "+ err);

});

const contentLength = response.headers['content-length'];

console.log("contentLength: " + contentLength);

let chunklength = 0;

response.data.on("data", (chunk) => {

   chunklength = chunklength + chunk.length;

   console.log("chunk-length-sum: "+ chunklength);

   writer.write(chunk);

});

response.data.on("aborted", () => { });

response.data.on("close", () => { });

response.data.on("end", () => { });

writer.on("finish", async () => { })

■Code Error Explanation

After the log reports an error, it will got to the 'aborted' event, and then directly go to the 'close' event, skipping the 'finish' event, resulting in interruption of uploading and downloading files.

↓Error log↓

at process.processTicksAndRejections (node:internal/process/task_queues:82:21) { code: 'ECONNRESET' }

■What I expect

Used the AXIOS with node.js can download large files or other methods can be used to download large files.

■Environment

node.js 18.7

AXIOS 0.26.2

■Question

1)Does Confluence Cloud have some limitations?

2)What could be the possible reason for this error (connResetException )and how to resolve it.
