Service call does not work from developer tools

Configuration
21

just as another FYI…

I just tried the following in yaml mode running 2021.6.4 and it worked as exprected:

service: light.turn_on
data:
  entity_id: light.basement_bath_light

it is a direct copy of the service data field:

ex

so there’s nothing wrong with the service itself.

Thanks for that confirmation. I can’t imagine a bug escaping attention. Must be something in my setup but I’m mystified as to what.
