Tried to install coroot on GKE - node-agents are all crashing with panics like this:

panic: interface conversion: bpf.MapValue is *lbmap.Backend4ValueV3, not *lbmap.Backend4Value

@chicagobuss, we've reproduced this issue and are currently working on a fix.

@chicagobuss , thank you for the report. Please update coroot-node-agent to the latest version (1.8.1)

chicagobuss commented 1 year ago

ya it's working great now with the 1.8.1 image

Can I ask how your tool works with dataplanev2 when hubble doesn't? how are they different?
