The following automation was working fine for more than a year, but suddenly stopped working in last few days.

service: light.turn_on
target:
  entity_id: light.canvas_ec3c
data:
  brightness_pct: 40
  effect: >-
    {{ ('Rings of Power','Higgs Boson','Purple Moonbeams','Great TV
    Background','Duo RED EDM','Vader','Pulse','Shooting Stars','Binding
    Lights','Nightclub','Color Burst','Falling Whites','Fireworks and
    Firecrackers','Flames','Forest','Inner Peace','Nemo','Northern
    Lights','Radial Sound Bar','Romantic','Triluminox Energy Crystal','Disco
    Color','Aurora magic','Christmas Lights','Stranger Things','Glowing
    Embers','Synthwave','Electric Purple')|random }}

Today I looked in Traces and saw the following error:

Stopped because an error was encountered at July 12, 2023 at 8:38:02 PM (runtime: 0.05 seconds)
Attempting to apply effect not in the effect list: 'Netflix and Chill'

What does this message even mean? The automation code is randomly choosing an effect from the provided list and applying it. So, the automation has selected the effect ‘Netflix and Chill’ from the effect list but is unable to apply it because it is not in the effect list? Please help.

Thanks…

Does the effect still there in nanoleaf app?
If not then this is a logical error.

Yes, the effect is there in the app. In Nanoleaf, the effects are downloaded to the panels. All the effects mentioned in the list are present and work fine from the app. When I change the effect from the app, HA also reflects the change right away.
