Harvester.create raises InvalidParameterException (flir Blackfly camera)

[oliver-batchelor]

Describe the Issue

I'm trying harvesters with our cameras and create on any of the devices raises an InvalidParameterException on one of the register_event calls. Any tips on why this doesn't work would be appreciated!

I'm on Ubuntu 20.04, Flir spinnaker SDK spinnaker-3.0.0.118-amd64. The cameras work with the usual PySpin API and they show up as GenICam devices, output of script is shown below.

Just installed harvesters from github. Python 3.8.

from harvesters.core import Harvester
h = Harvester()
h.add_file('/opt/spinnaker/lib/flir-gentl/FLIR_GenTL.cti')
h.update()
print(h.device_info_list)
ia = h.create(h.device_info_list[0])

Output from running this:
