error is: Invalid expmediaitem reference key for entity .; ID:

AI generated answer (using internal Slack threads):

The error "Invalid entity reference key" typically occurs when you are trying to reference an entity in NetSuite using an incorrect or non-existent internal ID or name. This can happen when you are trying to import data via CSV or when you are trying to set a value in a script. In the first thread, the issue was resolved by using the Internal ID in the CSV file for the import and selecting "Internal ID" from the dropdown after clicking the pencil icon on the left. It seems that the user had previously selected external ID, which was causing the error. In the second thread, the error "Invalid CUSTENTITYZUORASENDTOZUORA reference key" was encountered when trying to sync with a connector.

It was suggested to check if all the scripts deployed to the admin role are also deployed to the custom role. In the third thread, the user was trying to set a customer field value on a proposal and encountered the error "Invalid entity reference key". The solution suggested was to use the internal id of the customer when setting the value in a script. It was also mentioned that while
