Can't use an undefined value as a HASH reference

[Xord8664]

Hi! Trying to start this script on my server with ubuntu 22. Actually I have it working on an other server with this OS but can't figure out what I'm doing wrong now. My steps:

• apt update && apt install -y cpanminus libssl-dev libblas-dev gcc perl-openssl-defaults bzip2 libalgorithm-diff-perl libalgorithm-diff-xs-perl libalgorithm-merge-perl libdigest-hmac-perl libdigest-md4-perl libdigest-sha-perl libdpkg-perl libencode-perl libfile-fcntllock-perl libio-socket-ssl-perl libipc-system-simple-perl libnet-ssleay-perl libnetaddr-ip-perl libsocket6-perl liburi-encode-perl
• cd /home/chatbot/erebus/ && cpanm --installdeps .
• cd /home/chatbot/Mojo-Discord/ && cpanm --installdeps .
• cp -vr /home/chatbot/Mojo-Discord/lib/Mojo/* /home/chatbot/perl5/lib/perl5/Mojo/
• export PERL5LIB=/home/chatbot/perl5/lib/perl5/
• /home/chatbot/erebus/erebus.pl

apt install just for sure, but mb I need to install something else. Ofc config.yml changed and double checked. And I have this error at start:

Can't use an undefined value as a HASH reference at /home/chatbot/erebus/perl5/lib/perl5/Mojo/Discord/Gateway.pm line 259.

What did I miss? I have no clue in perl lang so it's very hard for me to traceback the issue. Can you help me please?
