Kibana version 8.17.0

Hi, I set up an index to store the alerts, Im using metric threshold and when I use the variable {{context.metric}} y get a JSON instead of just the value of the metric:

`{"condition0":"gcp.compute.instance.cpu.usage.pct"}`

Is this the normal behavior? or I am doing something wrong?

this is my document:

{  
"dataset": "gcp.compute",  
"fuente": "{{context.group}}",  
"razon": "{{context.reason}}",  
"metrica": "{{context.metric}}",  
"estado": "{{context.alertState}}",  
"@timestamp": "{{context.timestamp}}",  
"ctx\_cloud": "{{context.cloud}}",  
"ctx\_host": "{{context.host}}"  
}
