extracting json errors in lisa variables

In DevTest when using a JSON filter, if you enter in an expression path that doesn't evaluate (ex. an expression for getting a count and the path doesn't exist), the JSON evaluated return/response will be an error message.

 

This error message is stored in the Lisa variable.  Is there a way to literally test for this error message and replace it with a default value (i.e. 0) outside of writing a custom java step to interrogate the variable and replace it?  Or is there a way to have the JSON evaluation not return the error message but instead a desired default value?
