sync-full > TypeError: bytes or buffer expected, got <class 'str'>

[flinfo]

Context

Studio name: flux
Zou version: 0.19.12
Zou installation type: self-hosted x 2

Describe the bug
When trying the full-sync facility, I get errors, described below.

Expected behavior
Expecting a project db entrys to sync between 2 seperate instances.

Additional context
I have set up a second, identical instance of kitsu.
So we have Primary kitsu instance and a Secondary.
No problems doing a backup from Primary and restoring on Secondary.
But when attempt to sync to Secondary, it fails with the below errors.
I have created a dummy project on Primary for this testing called 'test4'

Issuing command:
SYNC_LOGIN="[email protected]" SYNC_PASSWORD="###################" zou sync-full --source https://testdomain.com/api --project test4

returns:

Start syncing.
