Error 500 sending inventory from agent

Hi,

I have OCS Server under Linux (docker) with 2.3.1 version. Agent on Windows computers is 2.3.1.1. Inventory has left of working in all computers, error 500 sending inventory.

It shows the next in activity.log:

I've activated loglevel and it shows now in the error_log of Apache the next:

DBD::mysql::db do failed: Unknown column 'O' in 'field list' at /usr/local/share/perl/5.20.2/Apache/Ocsinventory/Server/Communication.pm line 100.

DBD::mysql::db do failed: Unknown column 'O' in 'field list' at /usr/local/share/perl/5.20.2/Apache/Ocsinventory/Server/Inventory.pm line 70.

Someone can help me please? I don't know why it is happening this now. No changes in server. I don't know if a colleague has added some field in the ocs gui, is it possible?

Not sure, but line 70 is an insert in hardware table and line 100 is an update from same table.

Thanks beforehand.
