Loading "Device Description" in API fails with 500

[berkoben]

(using v2.1.1)

To Reproduce, go to any device (system is ALC) and click on the additional info button for "device Description". Then click on the "open in API" link. Result is the following:

500: Internal Server Error

There was an internal server error.

Thank you for reporting this. Could you make the port 47999 available? (Or a VLAN access?) This way I could determine the cause (Wacnet or ALC) and hopefully make a patch for it.

You can send me private info at cfortin@hvac.io

unfortunately we can't open up our network. If there's anything relatively straightforward I can do remotely, let me know

[Frozenlock]

Nothing comes to mind.

There is something you can try to go around this problem. If you're running Wacnet on your machine, go to http://localhost:47800/api/v1/swagger/index.html?url=/api/v1/swagger.json#!/BACnet/get_bacnet_devices_device_id_objects_object_id and enter the wanted properties, instead asking for all of them like the UI does.

At me too such problem. If you specify the required parameters, then the query is executed. How can I find out the list of all parameters for this object?

[Frozenlock]

I'll close for now as I couldn't reproduce the problem and there was many releases since then which might have fixed things.
