Anyone experiencing weird behavior related to this scenario? I have a clients-side script calling a Suitelet and it's passing the queryparameters and a console.log is showing that the correct parameters are being passed - params &type=unassignedrolls&key=3397&id=18638 but when I do a log.audit on the Suitelet it is not getting the value of the id parameter.

{
   id: "",
   type: "assignedrolls",
   script:4834,
   key: "3397",
   deploy: "1"
}

It worked in sandbox yesterday but all of a sudden it is not working in PROD or SB. The data is being retrieved from a saved search that is loaded via script.

Try using a prefix for your parameters, like

eric_b_id

- some query parameters might be reserved and will be consumed before being handed to your Suitelet.
