Can you list out the possible reason of UNEXPECTED_ERROR for record.submitFields

AI generated answer (using internal Slack threads):

The UNEXPECTED_ERROR for record.submitFields in NetSuite can occur due to several reasons: 1. NetSuite Defect: As mentioned in one of the threads, there could be a known NetSuite defect (like NS defect 604550) causing this issue. 2. User Event or Workflow Scripts: If there are any User Event or Workflow scripts running on Xedit, they might interfere with the record.submitFields operation and cause an unexpected error. 3. Custom Fields: As per one of the threads, the error occurs when trying to perform a record.submitFields against a custom field on an Inventory Status record. However, if you include a standard field in the same submitFields call, it works. Even stranger, if you include ANY field value that does not start with ‘custrecord’ (even if the field does not exist) then the submitFields will be successful. 4. External SuiteLet Form Issue: There could be an issue with the external SuiteLet form from NetSuite causing the error. Changing to record load/save might resolve the issue in this case. 5. NetSuite Updates: Sometimes, updates to NetSuite (like the 2021.2 update) might introduce new issues or bugs that cause this error. Remember, these are potential reasons and the exact cause can vary based on the specific context and code. Always ensure to debug and test your code thoroughly to identify the root cause. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
