Estoy usando PDFmake para generar archivos pdf en la aplicación Angular. Puedo generar todos los resultados requeridos usando la biblioteca pdfmake.

Pero obtengo 'Error de tipo de rechazo de promesa no manejado: nulo no es una función' este error en el registro de la consola como se muestra a continuación.
