IFTTT webhook integration KeyError: 'requestId'

Hi, I’m trying to integrate my HA in with web hooks. But for every request I get error like :KeyError: requestId. I didn’t found anything helpful in google. What I’m doing wrong ? This is my config from automations.yaml

- alias: IFFT
  trigger:
  - event_data:
      action: call_service
    event_type: ifttt_webhook_received
    platform: event
  condition: []
  action:
  - data_template:
      entity_id: '{{ trigger.event.data.entity_id }}'
    service_template: '{{ trigger.event.data.service }}'
  id: 1d39c9c1a7514b2488207b0da62f40c2

webhook body:

{ “action”: “call_service”, “service”: “script.turn_on”, “entity_id”: “script.play_google_home_radio” }

Same for me. Did You manage to solve it?

Hi, I had the same error and it took me quite a long time to solve it.
Solution is trivial: you just need to install IFTTT integration in HA (/config/integrations) and use newly displayed Webhook public URL. Thats all.
