Process model error: Expression evaluation error at function 'enumerate' [line 2]: Expression evaluation exceeds maximum allowed limits. (Data Outputs)

Question

Hi every one, 
 I got this error when running the code in process model. But when running it in a test expression rule, it didn't return me any error. Please have a look at the screenshots below:

I tried reduce the amount of data (from 91 to only 10) but the process error still occurred. 
 Do anyone knows the solution or possible reason for this? 
 Thank you!

mollyn126 Could you please verify the value of ac!numberOfDays by saving into pv!. Wanted to check what value is being generated to enumerate.

My initial thought would be enumerate is returning a negative value may be could you check it once. Could check your start dates and end dates once, is your start date less than the end date
