Office Scripts Custom Sort Failing During Automation

Please try

function main(workbook: ExcelScript.Workbook) {

    const sheet = workbook.getActiveWorksheet()
    const range = sheet.getRange("H3:J28")

    const rangeSort: ExcelScript.SortField = {
        ascending: true,
        key: 0,
        sortOn: ExcelScript.SortOn.value
    }

    range.getSort().apply(
        [rangeSort],
        false,  // case insensitive
        false,  // no headers
        ExcelScript.SortOrientation.rows
    )

}
