This is not a general issue, according to the code of this script and Judy's comments, this script seems designed to be run before ASIC instance database0 and database1 generate database-config.json.
For other code using load_db_config this issue should not happen.

I feel it is more like a timing issue as you pointed out, Can we call db_migrator, after /var/run/redis0/sonic-db/database-config.json is created ?
Here, https://github.com/sonic-net/sonic-swss-common/blob/7db6ccf5fb427d4832d6c54ab1f485ddd87b6697/common/dbconnector.h#L107 -- it doesn't make a difference if we pass/don't pass the namespace parameter to load_sonic_global_db_config()

I search sonic code but not found any code use the '-n' parameter of db_migrator.py to pass the namespace parameter.
I will add comments in the sonic-net/sonic-buildimage#18389 to ask author check if this can fix by your suggestion.
For load_sonic_global_db_config(namespace=args.namespace), I think it's better keep the parameter to keep the compatibility, incase we change the code of load_sonic_global_db_config in future.

@liuh-80 @judyjoseph all instance database@.service have dependency "Requires=database.service
After=database.service". db_mihgrator script in local host database will not be able to wait for all other instance ready unless we change the dependency.
