Exception in delivering result of invoking method

Hello peeps,

I’m getting an error

Exception in delivering result of invoking 'Cards.create': TypeError: Cannot read property 'cardTypeId' of undefined

What does the Exception in delivering result of invoking 'someMethod' mean?

All the data is there and everything works, so I’m not sure if I should be concerned about this error or not.

The method is failing. It looks like within the method you’re doing something like x = someObj.cardTypeId and someObj is null or undefined. Just a guess, without having actually seen any code.
