so in the stack trace it talks about line 66 but when i debug i can see
that
"camelContext.startRoute("salesforce-versions"); "
already in line 64 meaning the route is not started as the routeservices
object is empty (null). Which thereby causes and expection at line 66
which is
Endpoint ep = theRoute.getEndpoint();
I am wondering if there any specific call which adds all routes to the
camelcontext differently in 2.19.x compared to 2.20.0 ?
