I would like to propose moving the max chars into the node settings it’s self.
Every so often, we get asked as to why messages are being truncated, only to explain to the end user to change debug settings in the settings file.
I think moving this setting, into the node setting its self, will remove these instances of confusion, as I believe this will highlight to the user why they might see a truncated message, which they can address without raising the concern in thinking the runtime is truncating data.
