All the pathes inside the error message point to locally modified files or extensions.
/omd/sites/cmk/local/share/check_mk/web/plugins/wato/filesystem.py
/omd/sites/cmk/local/share/check_mk/web/plugins/wato/ovirt_plugin.py
/omd/sites/cmk/local/share/check_mk/web/plugins/wato/servicenow_ine
These three files are responsible for the errors. I don’t know what was changed there but they need to be also updated for the new version beforehand.
