QlikSense error General Script Error in statement handling question

[qwebnm]

A General Script Error has occurred.

After that, when I run the task in QMC again, it was successful.

It doesn't keep happening, but I want to know why the task that succeeds has an error.

May I know where is the problem?
If you need to check, please let me know how to check.

thank you.

Hello @qwebnm ,

One possible cause of this is null values, please see:

Otherwise, as this is taking place during a writeback, it's possible that the target was unavailable.  Were you able to further isolate this issue?
