You cannot submit this form due to an unexpected error.

AI generated answer (using internal Slack threads):

The "unexpected SuiteScript error" is a generic error message that NetSuite throws when it encounters an issue that it can't specifically identify. This error can occur due to a variety of reasons, and it's often challenging to pinpoint the exact cause without more detailed information. In the first scenario, the error could be due to a conflict with the scripts or workflows associated with the form. It's a good practice to deactivate all form scripts and workflows to isolate the issue. However, if the error persists, it might be due to other factors such as field settings, form configurations, or data issues. In the second scenario, the error might be related to the inlineedit sublist and the dynamic fields. The submit button posts to your suitelet, and you handle the record creation there. If the sublist uses all the fields of a custom record plus some dynamic fields set to disabled, it might cause issues. You might need to create a custom button to enable record creation. In the third scenario, the error seems to be related to the addSubmitButton function. This function doesn't have any required parameters, so it should work as expected. However, if the error occurs only when you add the addSubmitButton, it might be due to the way you're creating the form or other parts of your script. You might need to share what createForm looks like or try the process of removing parts of your script until it works. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
