Tengo una estructura de datos simple (elTransaction referenciado a continuación) para ser insertado en mongodb:

{"amount":111,"debitAcc":"588188286231743e7d5c923d","type":"CHARGE"}

Y obtuve la siguiente pila de errores:

Mi versión mongodb es3.4.2.

Lo interesante es que no tengo el problema en mi entorno de desarrollo local (mint linux 18.1). Pero simplemente no puede funcionar en mi entorno SIT, que es un ubuntu 16.04

¿Alguna idea?

Actualizaciones con código para insertar el documento.

El sistema funciona con otras escrituras (incluso con registros mucho más grandes)
