[jolo2486]

Describe the bug
After creating an account at https://iv.nboeck.de and clicking 'playlists' and then 'import/export' -> 'Import YouTube playlist (.csv) - browse' and picking a playlist csv file as downloaded from takeout.google.com, I get a page saying "It looks like you found a bug in Invidious!" with the following error:

I have tried several different mirrors, such as invidious.flokinet.to, and invidious.protokolla.fi, and also refreshing and trying again. I have also tried different playlists. Example of what they look like:
