Actions are not executed when loading script

[Juan]

I have configured action to be executed when the script is started, however when the interaction arrives to the agent, this action is not executed. I have tried to execute it directly from a button, but this one remains loading indefinitely. The script is intended to be deployed from a callback generated by the Genesys API, does this have something to do with not being able to execute the action, does the interaction must go through an ivr flow for my action to work?

I attach images of what happened:

Callback body:

{
  "scriptId": "52a640b9-22e...",
  "queueId": "c1baafc1-c023-...",
  "callbackNumbers": [
    "+34 93..."
  ],
  "callbackScheduledTime": "",
  "countryCode": "ES",
  "validateCallbackNumbers": true,
  "data": {
    "TIPO": "ENTRANTE"
  }
}
