Question:
Proton Orion Subscription - Error when parsing notification XML

Description:
I had configured Orion and Proton FIWARE Generic Enablers and made a subscription in Orion to send a notification to Proton when an entity of type Node is modified.

It happens that Proton is returning an error related with the parsing of the received XML.

proton | SEVERE: Could not parse XML NGSI event java.lang.NullPointerException, reason: null

I found that at least another user had posted a similar question but the answer to that question does not fits (and solve) my situation.

Thank you.
