I @Sandii I don't believe that is true. My search is as simple as they come

const getShippingZpls = ({ fulfillmentIds }) => {
    if (!fulfillmentIds)
        return []

    return search.create({
        type: "customrecord_roc_package",
        filters: [["custrecord_abc.custrecord_def", "anyof", fulfillmentIds]],
        columns: [search.createColumn({ name: "formulatext", formula: "{custrecord_zpl}" })]
    }).run().getRange({ start: 0, end: 1000 })
        .map(a => ({ zpl: a.getValue({ name: "formulatext", formula: "{custrecord_zpl}" }) }))
}
