You have entered an Invalid Field Value true for the following field: isperson

AI generated answer (using internal Slack threads):

The error message "You have entered an Invalid Field Value true for the following field: isperson" typically occurs when you are trying to set a value for a field that does not accept the value you are providing. In this case, the field 'isperson' is likely a checkbox field, and you are trying to set its value to 'true'. In NetSuite, checkbox fields usually accept 'T' or 'F' as values, not 'true' or 'false'. So, you should try setting the value to 'T' instead of 'true'. Here is an example of how you can do this:

javascript
record.setValue({
    fieldId: 'isperson',
    value: 'T'
});

If you are still facing the issue, it might be due to the field not being present on the form or the field being replaced by another field due to some feature being enabled. For example, in one of the threads, the 'issalesrep' field was replaced by 'sales roles' due to the 'team selling' feature being enabled. So, you might want to check if the 'isperson' field is present on the form and if it has been replaced by another field due to some feature being enabled. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
