[BUG] Mapped service call fails with xxx is not recognized as a template

Bug report

Description

Since migrating my controller due to a changed service call in Spotcast, the service call fails. The last two lines in the logs below are outputted without switching log level to debug.

In HA > Developer tools > actions I can run the exact same service call with succes. (Only diff is that service: must be action: in HA). I call the service with a long press on the two dots button which I can see in the logs is triggering correctly.

Since the service call is working from withing HA, I believe it is a issue with the otherwise great ControllerX project.

Other standard mappings on the same controller is working (removed below with [...])

Background: Since the HACS project Spotcast was forced to do a rewrite due to Spotify changing their API, a new service/action spotcast.play_media was made instead of the former spotcast.start.

I am aware that the currently working state of Spotcast is still an unstable alpha release. However, everything seems working at my end expect for this service call done through ControllerX
