Hi, using a JSON dump from a Vaultwarden instance, I get the following error :

$ bw2kp -o bitwarden.kdbx -i mydump.json
Master Password:

Apologies, I had a personal emergency and did not have the time to look into this issue.

I'm not sure how a null group was added for the given folderId. For now, I've added a check which will fall back to the root if this happens.

I've never used VaultWarden before, will create a sample vault and see if I can reproduce the issue.
