Adding Authors using SQL

Hi all.

I was having issues inviting Authors to write on my self-hosted Ghost page. I was continuously getting errors with the emails not sending so I manually added them and gave them roles by directly inserting them into the mysql database. When I try to add bios and other information for the authors I get an error at the top of the screen that says " Validation error, cannot edit user. Validation (matches) failed for id " Can someone point out how I can resolve this issue? Thank you.
