-------------------------------------

             Summary: Exchange body is null when using Mongodb changeStreams with update operation
                 Key: CAMEL-19470
                 URL: https://issues.apache.org/jira/browse/CAMEL-19470
             Project: Camel
          Issue Type: Bug
          Components: camel-mongodb
    Affects Versions: 3.x
            Reporter: Kevin Garrido


When using the mongodb component as a ChangeStreams consumer, the fullDocument is null for update operations. It's normal if we refer to [mongodb documentation|https://www.mongodb.com/docs/manual/reference/operator/aggregation/changeStream/].

 

As a temporary fix, you can use the object id to get the modified document with a route like this: 
{code:java}
from("mongodb:mongo?consumerType=changeStreams....")
.to(""mongodb:mongo?operation=findById"){code}
 

 

The MongoDbChangeStreamsThread.initializeCursor() method should be changed to use the fullDocument option when creating the iterable.
