Hi everybody, our team is struggling with implementing events in path planner. Every time we enable, we receive the following error:
“Unhandled exception: java.lang.NullPointerException: Cannot invoke “com.pathplanner.lib.PathPlannerTrajectory.getMarkers()” because “examplePath” is null.”
Here is the GitHub fork:
I think using PathPlanner.loadPathGroup(pathname, constraints) rather than loadPath should solve your issues
We fixed the problem with it not moving, and we tried PathPlanner.loadPathGroup(pathname, constraints) and the events were still not working.
We are using to autobuilder. We have a separate class loading the path group. Our sendable chooser returns the path group and then the autobuilder builds the auto using the same event map
Thank you. I tried using the RamseteAutoBuilder and it worked perfectly to load the eventMap.
