The code has DependencyInjection and already have all the required implementation. I am able to run in my machine as well as deploy in a test server. But when it is deployed in client machine where it is part of a main site. This is where this exception happens. I don't have control over this server, so clueless.
Any idea what might be going on here? Could it be the main site has a lower version of DependenyInjection that causes this error? Any insight would be much appreciated.
