File is not being completely updated on S3

Question

I have the following function that upload a file to a S3:

import {
  PutObjectCommand,
  S3Client,
} from "@aws-sdk/client-s3";

const client = new S3Client({
  endpoint: "https://fra1.digitaloceanspaces.com",
  region: "fra1",
  credentials: {
    accessKeyId: Env.get("BUCKET_KEY"),
    secretAccessKey: Env.get("BUCKET_SECRET"),
  },
});

const Bucket = "customers-space";

const Key = "customers.csv";

export const saveFileInSpace = async (path: string) => {
  const Body = fs.createReadStream(path);
  await client.send(
    new PutObjectCommand({
      Bucket,
      Key,
      ACL: "private",
      Body,
    })
  );
};

My file will be quite big (only ~50MB now, but will increase) so I used streams like the aws example.

However the call fails with the following:

     attempts: 1,
     totalRetryDelay: 0
   },
   Code: 'MissingContentLength',
   BucketName: 'customers-space',
   RequestId: '...',
   HostId: '...'
}

From the examples I found online no one used the ContentLength parameters.

I also use a stream, that does not have idea of his size.

Version of the sdk:

"dependencies": {
  "@aws-sdk/client-s3": "3.218.0",
  ...
}

What am I doing wrong?
