Missing inner instructions

[mohsen-vybenetwork]

Hi,
After upgrading the plugin to the latest version 1.16.x, we noticed that all the messages received in the transaction topic are missing inner instructions. I randomly checked a few signatures with Solscan, and in each of them, this section was absent from the messages within the transaction topic. It was fine with V1.14.x but has become problematic since we upgraded our plugin and RPC server.
As an example

All of this code drastically changed in cb9131b so it could be something broke.
