Error when running clear_cache command

Hi there, I try to run the command bench frappe --clear_cache and will receive the following error,

Traceback (most recent call last):

Can anyone help me to understand what is the error I am currently facing?

That is strange, can you check if all tables are there in the database? Did you drop tabSession by anychance (or tried to restore a backup?)
