zcl_cmd stopped working, now throws "'list' object is not callable" error

[defux-23]

I used zcl_cmd to send a custom cluster command for candle effect to a Hue Play. The code below worked fine until a few months ago:

action:` zha_toolkit.zcl_cmd
data:
ieee: light.hue_play_1_licht
manf: 4107
endpoint: 11
cluster: 64515
dir: 0
cmd: 0
args:
- 33
- 0
- 1
- 1

Then HA started to throw an error "'list' object is not callable" when this command should be executed.

It was not high on my priority list, but now I played around a bit to figure out how to fix it. I also tried to make a new command from scratch in a script with the visual editor in HA, but end up with the same error. Also tried to give the argument list as "args: [33, 0, 1, 1]", but this does also not change anything (and is retranslated by the visual editor to the above when switching back and forth anyway).

When trying around further, I also experienced also that the "dir: 0" forces HA to stay in yaml editor mode, as soon as it is removed it switches automatically to the input mask/visual editor (but that's probably not relevant, maybe just because the input mask has no field for "direction".

Strangely, even if I remove the "args:"-section completely, I still end up with the "'list' object is not callable" error. I also searched through different HA forums, but did not find any matching problem.

As the code above was working fine, I was wondering whether something was changed in the way lists of arguments are processed by ZHA Toolkit in one of the previous updates?

There have been changes lately:

• Allow passing keyword arguments in zcl_cmd #270 - 6aeffa3 - This does not seem to be the reason.

Somewhat related, but the issue was different.

• Changing SEA801 Thermostat setpoint - attr_write fails where GUI works fine #275 (comment) i

ZHA/zigpy has undergone quite a lot of changes itself and I think that zcl_cmd needs to be adapted to that.
Probably the list of bytes must be provided in a different way - I guess an objet with a method on it (probably to serialize the data) - I did not look at zigpy/zha for this.
