I would like to share some of my experiences while using QlikSense. I noticed some of the Script errors like missing a bracket ']' or a "," (Typo Error) , invalid path of variable of data connection path and some other are not explained properly in the log output error message.
the attached example I have attached indicate that there is a field missing.
It took some time for me to figure out the issue. it was a typo error.
i was left joining the table and the one of the field from the second table has an extra bracket-- > .... as [Surcharges]]
the error message did not help me to track and fix my script error.
