Community Tutorial: Follow a Spline and Report Distance Along It Using an Actor Component

It looks to me like you are missing all references to the Chaos Vehicles. That class is missing from the GetComponentByClass, and it says it can’t find the function “Set Steering Input” because it doesn’t understand what it’s referencing. Maybe this project doesn’t have that plugin enabled? Unfortunately simply enabling the plugin may still leave you with some broken links in the nodes, in which case you might try to migrate again or copy and paste some nodes.
