Hangs on parsing the Body

Hangs on parsing the Body

Closed this issue 2 years ago · 4 comments

As soon as I try to parse the Body stream using various methods the process hangs.
My sample code:

const s3Client = new S3Client({ endpoint: 'http://localhost:9000' });
 
const { Body } = await s3Client.send(
  new GetObjectCommand({
    Key: '...',
    Bucket: '...',
  })
);

const bodyAsString = await Body.transformToString();
console.log('bodyAsString', bodyAsString);

It doesn't throw nor it gets to console.log, it just hangs.
I also can't see any activity in the Access Logs.
Given the above I am not even sure if it hits the container.
I have mapped ui-shell.localhost to 127.0.0.1 in /etc/host

To help debugging I enabled logger on the S3 client and here's the output after the above GetObjectCommand:

Body is IncomingMessage - I guess that's why Body.transformToString() doesn't work?
Any ideas what could be wrong?

Hello @nkalinov 👋 Thanks for getting in touch. Unfortunately, I am not an expert in the library you are using. Can you please provide a repository with a minimal example? In this case, I could have a look myself.

Answer 2 · 2023-03-31T13:32:59.000Z

I'm using the latest official client - "@aws-sdk/client-s3": "^3.301.0"
Here's a simple repo with the script that I'm trying, hope that's useful - https://github.com/nkalinov/issue-repro-s3ninja
It prints "Body has transformToString method: true" and then hangs.

Hello @nkalinov! I just saw by coincidence that you have updated your comment with a link to an example – many thanks! And sorry for my late reaction, I do not get notifications for edits. In any case, I will have a look and get back to you asap.

Hi @nkalinov! I just happened to have time to check the reported issue. Your example did not work out of the box for me. I fixed it by adding a region and credentials to the configuration struct:

import {GetObjectCommand, S3Client} from '@aws-sdk/client-s3';
import {fromIni} from '@aws-sdk/credential-providers';

const s3Client = new S3Client({
    endpoint: 'http://localhost:9444',
    region: 'us-east-1',
    credentials: fromIni({profile: 's3ninja'}),
    forcePathStyle: true,
    ...

Using the latest versions of the SDK, ^3.353.0, all looks good here. I run S3 Ninja directly, outside of Docker, and I made sure that the object I am querying actually exists.

So, unfortunately, I do not see a way a change in this project could help you resolve the issue. I am sorry. 😔

Please reopen the issue if you have further questions, remarks, etc.
