What exact error will cause when a suitelet script try to modify a record during the beforeSubmit event execution

AI generated answer (using internal Slack threads):

When a Suitelet script tries to modify a record during the beforeSubmit event execution, it will throw an error. This is because the beforeSubmit event is a non-interactive event, meaning it does not allow for user interaction or modification of the record. If you attempt to modify a record in a beforeSubmit event, you will encounter an error similar to this: "SSS_INVALID_API_USAGE". This error message indicates that you are trying to use an API in a context where it is not allowed. Here is an example of how you might encounter this error:

javascript
function beforeSubmit(context) {
    var record = context.newRecord;
    record.setValue('custrecord_field', 'new value'); // This line will throw an error
}

In this example, the script is trying to set a new value for a custom field on the record during the beforeSubmit event. However, because this is a non-interactive event, the script is not allowed to modify the record, and NetSuite will throw an "SSS_INVALID_API_USAGE" error. To avoid this error, you should move any record modifications to the afterSubmit event, which is an interactive event and allows for record modification. Here is how you might modify the script to avoid the error:

javascript
function afterSubmit(context) {
    var record = context.newRecord;
    record.setValue('custrecord_field', 'new value'); // This line will not throw an error
}

In this modified script, the record modification is done in the afterSubmit event, so it will not throw an error. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
