no entiendo cual seria el problema, pense que era un error de mi aplicacion, pero genere otro proyecto de react para subirlo asi nomas como se genera, pero igual da el error, me parece raro por que antes de subir este proyecto subi mi backend y se desplego sin errores, pero me esta dando este error ahora, ayuda
