Describe the bug
The script doesn't work and get the following log after start:

Device and script details (please complete the following information):

• Shelly PlusI4 FCB467BAC924 | 1.0.8 | 58706c2c|
• Shelly BLU Button 1: 20230725-152141/v1.0.8@0ba28b97

UPDATE:
_It turns out that I had the option "Enable Bluetooth gateway" ON in the settings what was the reason the script didn't worked. By disabling the gateway function now the script works. Can someone explain this?

NOTE: in previous firmware this used to work when the gateway is enabled:
