Hello,
I am facing issue when I pass a malformed json.
I was testing on how the system would behave if I sent a malformed json. I
seem to get a jsonparse exception and the samza process terminates. Any
idea on what could be going on and how to mitigate this?
Exception in thread "ThreadJob" org.codehaus.jackson.JsonParseException:
Unexpected character ('D' (code 68)): expected a valid value (number,
String, array, object, 'true', 'false' or 'null')
