how can i fix this error when trying to selectnewline on a dynamically loaded custom record? "You have attempted an invalid sublist or line item operation. You are either trying to access a field on a non-existent line or you are trying to add or remove lines from a static sublist."

AI generated answer (using internal Slack threads):

The error message you're encountering, "SSS_INVALID_SUBLIST_OPERATION: You have attempted an invalid sublist or line item operation. You are either trying to access a field on a non-existent line or you are trying to add or remove lines from a static sublist," typically occurs when you're trying to manipulate a sublist or line item in a way that's not allowed. In SuiteScript 1.0, you're using

selectNewLineItem('item')

to create a new line item. However, you're trying to set the price before setting the item, which might be causing the issue. The order in which you set the fields matters. Try setting the item first before setting the price. In SuiteScript 2.0, you're using

selectLine()

in dynamic mode, which is correct. However, you're trying to get the value using

getSublistValue()

, which is used for static mode. In dynamic mode, you should use

getCurrentSublistValue()

. Also, make sure you're selecting the correct sublist. In your code, you're selecting a line on the 'item' sublist, but you're trying to get and set values on the 'expense' sublist. Make sure you're not mixing up the sublists. For the

Record.insertLine()

error, it might be due to the record type you're trying to insert a line into. Some record types do not allow line insertions. If you're in edit mode on an estimate, make sure that the sublist you're trying to insert a line into is editable. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
