Error in describing action: e.services[t] is undefined in automation shell_scipt

Dear Colleauges!

I try to run a curl in every 10 minutes via automation without success.
Do you have any idea?
Error message: Error in describing action: e.services[t] is undefined

configuration.yaml:

shell_command:
  domainupdate: "/usr/bin/curl https://www.myexternalurl.com/something"

automation.yaml:

alias: domain update
description: domain update
trigger:
  - platform: time_pattern
    minutes: /10
action:
  - action: shell_command.domainupdate
mode: single

As I tested the Error in describing action: e.services[t] is undefined errorcode caused by thi line:

  • action: shell_command.domainupdate

Thank you for your reply.
How can I work within the homeassistant container context? What and how should I modify?

Have a read of this topic:

Can you please give me a little bit more informations?
I am new in Home Assistant.

No. I would only be repeating what is in that post. Everything you need to know is in there.

Dear Colleauges!
