Error importing users into fresh database: 1048 Column 'uid' cannot be null

[mizziness]

Description

When importing users, all users with the admin role all return with an error and are not included in the import. The error looks like:

info	↳ Users: Match existing element with data {"username":"applausewebmaster"}.	5/22/2021 11:30 AM
info	↳ Users: Data ready to import {"username":"applausewebmaster","firstName":"applause","lastName":"webmaster","email":"[email protected]","preferredLocale":"","id":"1"}.	5/22/2021 11:30 AM
error	↳ Users: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'uid' cannot be null The SQL being executed was: UPDATE elements SET dateUpdated='2021-05-22 15:31:00', uid=NULL WHERE id=1 - Schema.php: 678.	5/22/2021 11:31 AM

Other users who were not admins import successfully.

Steps to reproduce

1. Have a Craft site with several users, some with the Admin role and some without.
2. Export all of the user data via Craft CMS gui (I chose extended JSON)
3. Create a new database, run Craft installation, and then sync your project-config - this creates the schema.
4. Use Feed-Me to set up a feed for the new database - the fields are 1 to 1 as it's the same site schema.
5. Run the import feed.
6. Get error.
