Hello,

On the Matter device, we register 200 channels in state.channelList.

channelList_full_200_entries.txt

When reading ChannelCluster.ChannelList from a Matter controller (matter.js),
we only receive about 30 entries.

channelList_read_result_30_entries.txt

Questions:

Is there any size limit for reading ChannelList in Matter or matter.js?
If a limit exists, is it configurable?

Thank you for your work on this project.

Ok in fact there seems to be a bug in the client side attribute decoding in 0.15.6 which prevents if from decode such multi message lists correctly when they are formatted as they are here. So updating to 0.16.x should already fix this.

Here is the device-side sample that we are using.
I’m attaching it here in case it helps with the investigation.

Ok, that looks strange ... I will check

@K-I-1912 Is the device you use also matter.js 0.15.6 as the shell app or an other version?

Apollon77 Apr 4, 2026

Ok in fact there seems to be a bug in the client side attribute decoding in 0.15.6 which prevents if from decode such multi message lists correctly when they are formatted as they are here. So updating to 0.16.x should already fix this.

Thank you for your response.
I have confirmed that the issue does not occur in version 0.16.10.
