REST API data connection error handling so the script will continue in case of error

Hi,

in my load script we are pulling data from many connections,

one of the connections is REST API.

but when the RESP API get error 400,500 etc.. the script fails.

1. how can i make the script continue even if the API failed?

2. or better is there error handling i can do? like try and catch?

You can use ErrorMode; you could set it to 0 before that specific load and back to 1 after

Argument Description

ErrorMode=1	The default setting. The script execution will halt and the user will be prompted for action (non-batch mode).
ErrorMode =0	Qlik Sense will simply ignore the failure and continue script execution at the next script statement.
ErrorMode =2	Qlik Sense will trigger an "Execution of script failed..." error message immediately on failure, without prompting the user for action beforehand.
