Error uploading BSON data


I am trying to UploadObjects to a live Storj V3 bucket from a golang program.

The data which is being uploaded is a BSON object.
This BSON data is fetched from a database which is currently of size 232 MB.

The error which I get is:

Additionally, if I just try to upload a BSON containing “Hello, Welcome to Storj” then I do not get the above error message.

Please guide me on what the error means and how can I resolve it.

Could you post the part of the source where you are configuring the uplink and uploading the file please?
