Issue Summary

The space export download is incomplete.

Steps to Reproduce

1. Create a space export.
2. Download the export file.

Expected Results

If the space export file is 1.4 GB the downloaded file also should be of the same size.

Actual Results

The download shows the total attachment size, but the download is terminated early, which results in a corrupted file. 

For example: If the total file size was 1.4 GB the downloaded file was 300 MB.

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available
