I am trying to setup a pwm controlled on-off switch

I am trying to setup a pwm controlled on-off switch for Led's on heater 4

So I placed a "M307 H4 A-1 C-1 D-1" at the bottom of the config.g
and if I try to use the pin with a command like "M280 P4 S160 I1"
It will not work and I get an error message of

M98 P"0:/macros/LED/LED off"
Error: M280: Invalid servo index 4 in M280 command

And i know the switch works because if i put the signal wire for the Pwm switch on heater 3 (My bltouch pwm signal) it works perfect. so i'm missing a step in the process to get this working

What controller are we talking about?
You might have a FET behind Heater3, but not behind Heater4. Because heater 4 is only a GPIO pin leading to a sub-controller like DUEX...

Are you sure you're on RRF 2.05.1?
Do you have a config-override.g that contains another heater command M307 H4?

Thanks u nailed it a config override was auto generated with M307’s for all heater’s. For some reason setting a probe type for a heater overrides the M307 with blank pid’s in config override which is why the bl touch worked and pwm switch did not.....I guess?
