Help: Error when trying to add a SceneControlButton

Hello, I ran into an error when trying to add a SceneControlButton. Code: 
Hooks.on("getSceneControlButtons", getSceneControlButtons);

function getSceneControlButtons(controls) {
  if (canvas == null) {
    return;
  }
  controls.push({
    name: "markers",
    title: "Markers",
    icon: "fa-solid fa-location-pin",
    layer: "markers",
    visible: true,
    tools: [
      {
        name: "create-marker",
        title: "Create Marker",
        icon: "fa-solid fa-location-pin",
        button: true,
      },
    ],
    activeTool: "marker",
  });
}
Hooks.on("getSceneControlButtons", getSceneControlButtons);

function getSceneControlButtons(controls) {
  if (canvas == null) {
    return;
  }
  controls.push({
    name: "markers",
    title: "Markers",
    icon: "fa-solid fa-location-pin",
    layer: "markers",
    visible: true,
    tools: [
      {
        name: "create-marker",
        title: "Create Marker",
        icon: "fa-solid fa-location-pin",
        button: true,
      },
    ],
    activeTool: "marker",
  });
}
The button is added, but when clicked I get an error in the console: 
Uncaught TypeError: Cannot read properties of undefined (reading 'activate') 
    at SceneControls._onClickLayer (foundry.js:81634:42)
    at HTMLLIElement.dispatch (jquery.min.js:2:40035)
    at v.handle (jquery.min.js:2:38006)

I am at my wit's end. Any and all help would be appreciated.
Solution:
created the “markers” layer and added it to the canvas?

also set as activeTool “marker” and your tool is called “create-marker”
