Exception with DiscoveryInterfaceEvent
Hello,
we run 3 Mako G 319c in an industrial setting and recently noticed the following exception after running the system for 557689 frames:
Exception ignored on calling ctypes callback function: <bound method _BaseFeature.__feature_cb_wrapper of Feature(_handle=c_void_p(1),_info=VmbFeatureInfo(name=b'DiscoveryInterfaceEvent',featureDataType=<VmbFeatureData.Enum: 3>,featureFlags= <VmbFeatureFlags.Read: 1> <VmbFeatureFlags.Undocumented: 4>,category=b'/Discovery',displayName=b'Discovery Interface Event',pollingTime=0,unit=None,representation=None,visibility=<VmbFeatureVisibility.Beginner: 1>,tooltip=None,description=b'Indicates the last interface discovery event.',sfncNamespace=b'Custom',isStreamable=False,hasAffectedFeatures=False,hasSelectedFeatures=False))>

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
IndexError: pop from empty list
What is the cause of this? Should this maybe be mitigated by checking if the list is empty before popping it?
Are you using the latest release? Does this error happen when you connect or disconnect a camera?
Yes latest release. We did not wilfully connect/disconnect any cameras. Maybe a camera resetted itself?
@Teresa-AlliedVision @NiklasKroeger-AlliedVision What is going on with customer support? We have about 25000 € of these cameras installed. And this seems like a rather simple error to fix.
For immediate support needs, please contact customer support through us or the distributor the cameras were bought from. https://www.alliedvision.com/en/about-us/contact-us/technical-support-repair-/-rma/
pinging @Teresa-AlliedVision @NiklasKroeger-AlliedVision Still no feedback from your support team ONE MONTH AFTER filing the ticket.
