Error "General Script Error in statement handling" when reloading Qlik Sense app

[Sonja_Bauernfeind]

Storing a table containing NULL value to a txt or qvd file fails with error General Script Error in statement handling

For example, the following piece of the script fails with the above error when executed:

DataTable: 
LOAD * INLINE [ 
NP 
1 
]; 

LEFT JOIN
LOAD  * INLINE [ 
NP, AD 
2, test 
]; 

STORE AD FROM DataTable INTO [lib://Temp/test.csv] (txt); 

Environment:

• Qlik Sense Enterprise on Windows , November 2018 IR to Patch 4 versions

Resolution:

• Verify if there are extra and unintended characters in any of the column names (blank spaces, extra letters). Remove them and run the script again. In addition, see IsNull - script and chart function which may help with troubleshooting.
• Verify that sufficient disk space is available. 
• This issue was reproduced in lab only in the November 2018 releases and not on newer builds. There was no fix officially produced for the problem found on November 2018. Note that November 2018 is no longer a supported version, so upgrading to a newer release to check if issue is resolved would be required.

Saw the error in QlikView 12.80 today:

20250402T201038.149+1300 General Script Error in statement handling
20250402T201038.151+1300 Execution Failed
20250402T201038.154+1300 Execution finished.

It was loading data through API. Error was not happened in the same place every time. For example it occurred when loading table A this time, but when I re-reloaded it without making any changes, it occurred in table B next time!
