The prize is not delivered

Hello again. My players do not receive the prize for winning the event. I have tried several configurations but when the event ends the prize (scrap) that I have configured is not delivered. I attach the part of the config file that I think is the relevant one. Any ideas?

"Prize settings": {
    "How many prizes should the player receive per claim?": 1,
    "Prizes": [
      {
        "shortname": "scrap",
        "min_quantity": 500,
        "max_quantity": 500,
        "skin": 0,
        "displayName": null,
        "dropWeight": 1
      }
    ],
    "Economic dollars for winning a match [requires: Economics]": {
      "min_amount": 0,
      "max_amount": 0
    },
    "Server reward points for winning a match [requires: ServerRewards]": {
      "min_amount": 1000,
      "max_amount": 1000
    }
  },

Hey mate are they using the command to redeem the prize?

/sprize from memory.

Oops, I didn't see that command anywhere. Sorry for the inconvenience, you can close the ticket. Thank you very much for your help.
