Question:
Is Orion compatible with AWS DocumentDB

Description:
I am trying to connect Orion with AWS DocumentDB but it's not getting connected. However I tried two other FIWARE components IoTAgent and Sth-Comet with DocumentDB and both are working fine.
Same hostname and credential are working for IoTAgent and Sth-Comet. I also checked for the connectivity, which is fine, as IoTAgent and Sth-Comet are in same network. I also checked from a different mongo host in same network and this also worked. Below is the error that I am getting for Orion.

Is there any possibility that Orion is not compatible with AWS DocumentDB?
