Tengo la siguiente advertencia (verifique la línea comentada en el código) y no sé cómo agregar el objeto promise() ya que mi función no es asíncrona.

 function MostProfitable() { var max = 0; var id; for (var i = 0; i < minmaxcoins.length; i++) { if (Number(minmaxcoins[i][4]) > Number(max)) { max = minmaxcoins[i][4]; id = i; } } try { if (minmaxcoins[id][4] >= 0.6) { // error at this line console.info('Max coin: ', minmaxcoins[id][0], ' ', minmaxcoins[id][1]); console.info('Min coin: ', minmaxcoins[id][2], ' ', minmaxcoins[id][3]); console.info('Profit: ', minmaxcoins[id][4], '%'); const d = new Date(); opportunity = opportunity + 1; console.info( opportunity, ' ***********************************************', d ); begin(); } } catch (error) { console.error(error); begin(); } }

aquí está el error/advertencia:

Sé que es solo una advertencia, pero noté que la aplicación falla, ya que debería funcionar las 24 horas del día, los 7 días de la semana, sin parar. ¿Alguien puede explicar este problema?
