Assets corrupted on export

[Guyda]

All the downloaded image and video files from the export are corrupted. I've tried this on two different spaces with the same issue.

Expected Behavior

Content and assets exported from Contentful to my local machine.

Actual Behavior

Assets turn out to be corrupted on cli export

Steps to Reproduce

Running my command

contentful space export 
    --space-id <space_id>
    --management-token <cma_token> 
    --environment-id master 
    --export-dir contentful_exports/test 
    --save-file 
    --max-allowed-limit 1000 
    --download-assets

Returns this

The export took 1 minute (42s)

Opening any files from the export with the preview app in OSX:

Tested with ImageMagick

magick 96.jpg -strip fixed-96.jpg
magick: Not a JPEG file: starts with 0xef 0xbf `96.jpg' @ error/jpeg.c/JPEGErrorHandler/356.

One thing I noticed in the export is when it's downloading the assets it says unknown in the terminal see sample here. Is it not detecting the file format?

downloaded unknown (//images.ctfassets.net/<space_id>/<uid>/96.jpg etc...

Environment

Node: 20.17.0
Npm: 10.9.0
Contentful: 3.7.1
Operating System: OSX 15.2

I have also experienced this! Version 3.7.0 works as expected but bumping to 3.7.1 caused issues.

Confirming going back to v3.7.0 fixes removes my problem. Thank you.
