I am trying to pass an array to a function, and later on doing a .push to that function, but it gives me an error: "main.js:500 Uncaught TypeError: arrayTemperaturaPotTemp.push is not a function"

First of all, Im inside a function, where I declare all variables, but the importants are:

let arrayTiempo = new Array, arrayTemperatura = new Array, arrayTiempoPot = new Array, arrayPotencia = new Array, arrayTemperaturaPotTemp = new Array, arrayPotenciaPotTemp = new Array;

And now I call a function to which I pass the next data:

iniciarGraficos(arrayTiempo, arrayTemperatura, temperature, pos, subcadena, ocurrencias, tiempo, valor, valorMedio, ultimaHora, ultimaTemp,
arrayTiempoPot, arrayPotencia, energy, posEner, subcadena, ocurrenciasEner, tiempoEner, potencia, potenciaTotal, ultimaHoraEnerTiemp, ultimaEnerEnerTiemp,
ultimaHoraEnerTemp, ultimaEnerEnerTemp, ultimaTempEnerTemp, arrayTemperaturaPotTemp, arrayPotenciaPotTemp, valor, potencia);

Inside this method, I don't use "arrayTemperaturaPotTemp" yet, but I pass it to another method:

function iniciarGraficos(arrayTiempo, arrayTemperatura, temperature, pos, subcadena, ocurrencias, tiempo, valor, valorMedio, ultimaHora, ultimaTemp,
  arrayTiempoPot, arrayPotencia, energy, posEner, ocurrenciasEner, tiempoEner, potencia, potenciaTotal, ultimaHoraEnerTiemp, ultimaEnerEnerTiemp,
  ultimaHoraEnerTemp, ultimaEnerEnerTemp, ultimaTempEnerTemp, arrayTemperaturaPotTemp, arrayPotenciaPotTemp){

if ((pos = temperature.indexOf(subcadena, pos)) !== -1) {...}

if ((posEner = energy.indexOf(subcadena, posEner)) !== -1) {...}

actualizarGrafico3(arrayTemperaturaPotTemp, arrayPotenciaPotTemp, valor, potencia, "MiGraficaEnerTemp", 50_000, 72_000);
}

And now, when it reaches the function "actualizarGrafico3", that has the next content:

    function actualizarGrafico3(arrayTemperaturaPotTemp, arrayPotenciaPotTemp, valor, potencia, nombreGrafica, min, max){
             arrayTemperaturaPotTemp.push(valor);
             arrayPotenciaPotTemp.push(potencia);
    }
