Empty page browsing EP3 in Python Matter Server UI

[lboue]

Issue

Hi,

I am testing Matter Silabs dishwasher example with Silicon Labs EFR32 board and I am facing an issue:

When browsing EP3 in Python Matter Server UI, the page is empty. It's as if the process has stopped. EP3 has 2 clusters:

• DeviceEnergyManagement ClusterId 152 (0x0098)
• DeviceEnergyManagementMode ClusterId 159 (0x009f)

It works fine for EP1, EP2

Is there a way to enable debug?

Is there any way to catch the exception to avoid a blank page and display an error message instead?
