How to send the file from S3 to Client with response ?

[bumjun-kim]

I am trying to make a download API for client based on TypeScript.

Object can be read from S3, but cannot send it to client with response for some reason.

Can anyone find what I made wrong?

Below is my code...

    downloadFile = async (req: Request, res: Response): Promise<void> => {
      const fileName = 'folder/3c96c1b';

      const getObjectCommand = new GetObjectCommand({ Bucket: config.awsS3Bucket, Key: fileName });
      const result = await awsS3.send(getObjectCommand);

      if (result.Body) {
        const stream = result.Body as Readable;

        console.log(111, Object.keys(result.Body));

        stream.pipe(res);
      }
    };

Hi @bumjun-kim - thanks for reaching out.

I'm not sure what you mean by cannot send it to client with response. I don't see anything wrong with the code you have on GetObjectCommand. Are you getting any errors?
