Mailchimp Extension

I am having difficulties in installing it. I am using SuiteCRM 7.1.4 with MariaDB 10.6 in a docker-compose environment adapted from the one provided by Bitnami here. I am using that version since it is the last one provided with PHP <8 in order to be compatible with ionCube Loader. After installing the ionCube, the import stops at “Installing Bean : smack_Mailchimp_Lists” (see attachment ). The logs show the following messages:

Can you help on how to solve it or how to workaround this error?
