Grocy Shell Command Error

I’m having issues with this tshell command that I’m trying to use on my grocy addon to execute a chore and I’m hoping I can get some help.

grocy_track_chore:

"curl -X POST http://192.168.1.11:9283/api/chores/{{chore_id}}/execute -H 'Accept: application/json' -H 'Content-Type: application/json' -H 'GROCY-API-KEY: {{grocy_key}}' -H 'cache-control: no-cache' -d '{ \"tracked_time\": {{tracked_time}},  \"done_by\": 0 }"

The error that I’m getting is:
Template variable warning: ‘tracked_time’ is undefined when rendering
