Después de actualizar de Webpacker 4 a 5, recibo un nuevo error al ejecutar Rails webpacker:compile. Ejecución de desarrollo de hilo, solo; funciona sin problemas: parece que no puedo encontrar la causa de este error o en qué archivo se encuentra. No hay muchas herramientas de depuración en este caso. ¿Cómo soluciono el problema donde splitChunks falla para webpacker 5?

Error:
