Error restoring JSONs to MongoDB in `0 - Load Data`

[garandria]

I am trying to run the noteboook 0 - Load Data and had an issue on the Restore JSONs to MongoDB cell. I have already downloaded repositories.json.gz and runs.json.gz as mentioned in the README. More details below:

gha-dataset/jupyter $ ls
'0 - Load data.ipynb'  '1 - Dataset metrics.ipynb'   repositories.json.gz   runs.json.gz
gha-dataset/jupyter $ file repositories.json.gz
repositories.json.gz: gzip compressed data, from Unix, original size modulo 2^32 69208463
gha-dataset/jupyter $ du -sh repositories.json.gz
67M     repositories.json.gz
gha-dataset/jupyter $ file runs.json.gz
runs.json.gz: gzip compressed data, from Unix, original size modulo 2^32 1063390519 gzip compressed data, reserved method, has CRC, from FAT filesystem (MS-DOS, OS/2, NT), original size modulo 2^32 1063390519
gha-dataset/jupyter $ du -sh runs.json.gz
964M    runs.json.gz

Now, when I run the cell mentioned above, I get the following enconding error:

---------------------------------------------------------------------------

Any idea?
