Errors when running remote.send.command script

Hi all,
I’m trying to create a remote.send.command trigger on my Broadlink RM4 emitter. The script works when triggered but I get a “command not found, exiting sequence” error message. Not sure what’s going on?

The script is as follows:

alias: CK Fan Power
sequence:
  - service: remote.send_command
    data:
      command: >-
        b64:
        JgBsAHBwHFUcVB0cHFUcVB1UHB0cHB0cHB0cHRxUHB0cHRxUHRwcHRwcHVQcVRxUHVQcVB0cHQAEWHFwHVQcVB0cHFUcVB5THB0cHB4bHB0cHRxUHRwcHRxUHRwcHRwcHVQcVR5SHVQcVB0cHQANBQ==
    target:
      area_id: ck
      entity_id: remote.rm4_ck_remote
mode: single

Error logs show this:
