CRM Dynamics Plugin Error - Given Key not found in Dictionary - dictionary

Question

Hi i developed a plugin and once deployed, i'm getting an error on save of a record.
Given key was not found in Dictionary. It's a pretty generic error, do you see anything or possibly know of a way to go about debugging ? `

Its better to check before we are trying to access any attribute in an object.
In this particular code, one catch is that while accessing the images we are not trying to check whether the object contains that image or not.
Similar way check any other miss.
It may also be possible that we are checking for a particular attribute and accessing a different one because of a typo.
Hope this helps you to pin point the issue.
