Regarding issue on my Mautic

My Mautic version is: 4.4.9
My PHP version is: 8.0.29
My Database type and version is: 5.7.23- |Doctrine driver|pdo_mysql|
This is my current workflow campaign structure in Mautic which is executed based on when a contact utm field will contain “Home” and lead stage should be “Lead” then this workflow will trigger E.g I just run the workflow according to utc time 11 am right now(Wednesday)

It executed the workflow of 11 am but when I see contact event it give 500 internal error. Please see attached screenshot below:

These errors are showing in the Mautic log :
[2023-08-09 01:00:03] mautic.WARNING: MaxMind license key is required. {“hostname”:“vultr”,“pid”:571737}
[2023-08-09 01:00:03] mautic.ERROR: Failed to fetch remote IP data: URI must be a string or UriInterface {“hostname”:“vultr”,“pid”:571737}
[2023-08-09 01:00:03] mautic.WARNING: MaxMind license key is required. {“hostname”:“vultr”,“pid”:571737}
Please let me know what is the issue and how to fix this all? Thanks

Greetings of the day,
Could someone please explain how a plugin bundle works, including the flow of data within the bundle, i.e., the process of transferring data from one file to another?
Thanks for your Consideration,
