Error with djigger in agent mode (java.io.InvalidClassException)

When trying out the newer features of the develop branch in djigger, I'm running into the following exception (see below). Not sure what I'm doing wrong.

Unexpected error
java.io.InvalidClassException: io.djigger.monitoring.java.model.ThreadInfo; local class incompatible: stream classdesc serialVersionUID = 2091258603924023895, local class serialVersionUID = 4152628234709390380

Solution

  • You're probably using an incompatible version of the agent.jar with the client. Try rebuilding the agent and redeploying.
