Necesito acceder a "no", pero arroja como indefinido.
Desde tu
console.log("vvvvvvv", newdata[0].salesOrder); devoluciones de declaraciones
{ salesOrder: [ 623d917d4c9f21730ace6256, 623da8bbeae48b2f34372a95, 623da8bbeae48b2f34372a92, 623d98964c9f21730ace642c ], no: [ null, '0900009293', '0900009294', null ], }su iteración debe ser como la siguiente
let nullInvoices = []; console.log("vvvvvvv", newdata[0].salesOrder); for (let i = 0; i < newdata[0].salesOrder.no.length; i++) { if (newdata[0].salesOrder.no[i] === null) nullInvoices.push({ SO: newdata[0].salesOrder.salesOrder[i], invoice: newdata[0].salesOrder.no[i], }); }Ejemplo de implementación
