hi

the expression is : logical.ifFunc(text.right(HBYWLB,1)=='B',-1,1)
the logical and text in the expression are coustomize bean.
I test the expr if run fast it will error every time.
but when I sleep(10) the code every execute ,it's will be fine.

if I run the expr with multi thread it also error.

and if the expression set with bellow:
logical.ifFunc(text.right(HBYWLB,1)=='B',-AAA,AAA)

it's run fine.

needs help.

error message is:
