“message”: “Applications failed to close normally. Object reference not set to an instance of an object. at Source: Read Range”,Please tell me how to handle them?
Object Reference
Whatever the excel file path or the CSV path you have provided in read-rang that file might not be exist. or if you are using any variable in read range property that variable value might be null, check those and then run it.
Not working
If you give write line or message box to check those values, you will give the same error because you are getting null values from the config. Check if you are reading the config file correctly
