Multiple workflow runs API

Actions
1

Hi,

I’m running into a problem that i can’t find the solution for.
i got a workflow:

name: NetBox - Add Device
run-name: "NetBox Add: ${{ inputs.name }} (${{ inputs.ip }})"
on:
  workflow_dispatch:
    inputs:
      name:
        description: 'Device Name'
        required: true
      ip:
        description: 'Device IP'
        required: true
      port:
        description: 'SSH Port'
        required: true
jobs:
  add_to_netbox:
    runs-on: debian-latest
    container:
      image: urlfor/test/netbox-run/netbox-runner:latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4
      - name: Run NetBox Add Device
        env:
          NETBOX_URL: ${{ secrets.NETBOX_URL }}
          NETBOX_TOKEN: ${{ secrets.NETBOX_TOKEN }}
          DEV_NAME: ${{ github.event.inputs.name }}
          DEV_IP: ${{ github.event.inputs.ip }}
          DEV_PORT: ${{ github.event.inputs.port }}
        run: |
          # pynetbox is already pre-installed in the image!
          python3 netbox_scripts/add_device.py

when i run multiple posts to the api like this:

URL/api/v1/repos/test/netbox-automation/actions/workflows/netbox%2fadd_device.yaml/dispatches

call 1

{
"ref": "master", 
"inputs": {
  "name": "FW01",
  "ip": "15.15.15.15",
  "port": "22"
  }
}

call 2

{
“ref”: “master”,
“inputs”: {
“name”: “FW02”,
“ip”: “16.15.15.15”,
“port”: “22”
}
}

the first one gets canceled and the last one is finished.
any idead how to fix this?
