------------------------------------
Summary: Reserved PubSub attributes are unintentionally passed on
causing send to fail
Key: CAMEL-15617
URL: https://issues.apache.org/jira/browse/CAMEL-15617
Project: Camel
Issue Type: Bug
Components: camel-google-pubsub
Affects Versions: 3.5.0
Reporter: Alvin Kwekel
When Camel receives a PubSub message with reserved Google PubSub attributes
these are set on a Camel header and passed on to any message sender. These
reserved attributes are not allowed to be set on an outgoing message so this
throws an error.
1) We can filter out these reserved attributes before sending.
2) We could also use another Camel header to store the reserved attributes
which will not be used when sending.
3) We could also map all attributes to headers and vice versa like we do with
other transports. The real issues with this is that PubSub only supports string
values as attributes. And we still need to filter out the reserved attributes.
I've already prepared a fix based on the proposed solution: 1.
