The patch cannot be operated(when using MQTT)

Dear, Cables Community

I would like to link M5Stack and cables.

When saving using MQTT Ops, the patch cannot be operated.
It looks like the attached image.
There is no error when just cloning the sample patch, but it seems that an error occurs when changing the data of MQTT Ops.

Is there a way to solve it?

The development environment is Mac OS / Chrome.

Thanks.
