Hello,
I have this small use case where I have to input the test marks for a specific student using the Script task, a decision must be taken if the avarage of the test is greater or less than 50 for which i used the Gateway(XOR) the. i have the User task for the administrator to approve or accept the student to the next grade and the end process but when i try to run it i get this error.
What may be the cause of these error?
