- Server operating system version
- Ubuntu 22.04 LTS
- Plesk version and microupdate number
- 18.0.62 #2
In the 'List of subscriptions' I selected the subscriptions I wanted to migrate, then the content that must be transferred:
- Copy to source customer/reseller
In the end no subscription was loaded for migration and the error message appeared
Failed to fetch configuration data from Plesk servers
Cause: Object of type filter is not JSON serializable
That is a critical error, migration was stopped.
I have no clue what this message means and how to solve the issue, any suggestions?
Thanks in advance
