Date/Time Error: (Operation value must be a string (customfield_10153))

[ryan.zore]

I have created a rule to compare a dropdown field and assign a date {{now.plusDays(14)}} to a Date Picker field and am getting an (Operation value must be a string (customfield_10153)) error when the rule runs.

Hello @ryan.zore 

is customfield_10153 the Date Picker field to which you are trying to assign a value?

Have you used the Log Action action to see what value you actually get when you use {{now.plusDays(14)}} ? 

Can you show us the entire rule and the details of the component where you are trying to assign the value?

Hello @Trudy Claspill thank you for your reply.  I wasnt able to get the debug command to work properly but have attached screenshots for your review.  

Also, the custom field ID is 

"customfield_10191":"SLA Due Date"

Your rule indicates you are editing two fields; "SLA Due Date" and "Advanced". What is the "Advanced" field?

The error message in the log is referencing customfield_10153. What is that field? Is that the "Advanced" field?

This is what the Log Action action needs to look like to log the value to the rule Audit Log.
