Well, to clarify... If you want to use the Expression ${field.value} then 
you'll want to use the Replacement Value Strategy of "Literal Value." When 
you're doing is evaluating the RecordPath, getting the value as the variable 
${field.value} and then attempting to evaluate that as a RecordPath. So if 
//log_date evaluated to say "01/01/2019" then the way you have it configured, 
it would be attempting to evaluate "01/01/2019" as a RecordPath, and that's why 
it is failing. Changing the strategy to Literal Value means that you would set 
the value "01/01/2019" as the value for the field (i.e., you would not be 
changing anything).

Thanks
