Hokutor updated CAMEL-16480:
----------------------------
Description:
I just upgraded from camel 3.4 to 3.8. I had a logger statement as follows in
my application. I was printing exchange body as follows in a log statement
.log("API response received is ==> ${body}")
Prior to upgrade, the above log statement prints the exchange body perfectly by
evaluating ${body} expression
However, after upgrade, it prints as following
API response received is ==> body
On further digging, just figured that if you happen to add a property with key
"body", then it causes the above unexpected behavior. Attaching a screenshot
which illustrates the problem with a simple camel route
This issue was also discussed on zulip -
