From the SystemOut log:
Caused by:

有人知道我为什么会收到此错误吗?
Does anyone know why I'm getting this error?
此处的相关问题: Maximo公式可以返回null吗?
推荐答案
据我所知，此preSaveEventAction方法不期望null值，并且会自动崩溃.查看Javadoc中的com.ibm.tivoli.maximo.expression.Expression.eval()方法.它正在返回BigDecimal，这是公式应返回数字的线索.
From what I see, this preSaveEventAction method is not expecting a null value and voluntarily crashes. Look at the com.ibm.tivoli.maximo.expression.Expression.eval() method from the Javadoc. It is returning a BigDecimal, a clue that a formula should return a number.

所以出现此错误的原因似乎是因为您的脚本返回了无效的值，与此处相同:
So the reason you're getting this error seems to be because your script returns an invalid value, same as here: Can Maximo formulas return null?
