have you found a solution?

I am facing the same error:
Creating label No leídos
400: Invalid label name - invalidArgument

This is a mbox created by Takeout.
No leídos means Unread, it is not really an existing label.

I have tried playing with all possible variants of writing "No leídos" with --extra-reserved-labels and --extra-system-labels, to no avail…

[mdesdin]

Takeout translates labels, GMAIL native/system labels, and then GMAIL is not aware when importing back. Or maybe there is a way to set the language in GYB when importing?

[mdesdin]

For spanish, these labels need to be replaced:

(no the ones that are the same, like Notes/Notes)

something like this should do it: sed -i -e '/X-Gmail-Labels/s/No_le=C3=ADdos/Unread/' mbox-file-here
