[ENHANCEMENT] More context logged for errors

[szesch]

Describe the enhancement
It's currently difficult to debug unexpected panics and errors. It's not always clear what file, resource, attribute, etc. that is failing. It would be help to provide more context in these error messages so as a user I know what to start looking at.
