Illegal invocation when targeting a container

[danDanV1]

I get the following error when trying to horizontally scroll a container:

vendor.js:80624 Uncaught TypeError: Illegal invocation
    at Class.<anonymous> (vendor.js:80624)

// scroll x axis
 scrollTo(eases[index] * targetX * dirX + offsetX, startY);

Logger immediately preceeding returns the following:
0 500 "tx:480, ty:NaN, ox:0, oy:undefined, x"

Invoked via (for debugging):

this.get("scroller").scrollTo(0, 500, {
    axis: "x",
    container: "scrollable-in-viewport",
    duration: 500
  });

On the following template:

  <div
    id="scrollable-in-viewport"
    style="overflow-x: scroll;
  overflow-y: hidden;
  white-space: nowrap;
  height:100vh;"
  >
    ...many image components...
    <div
      class="bg-grey-darker"
      style="display:inline-block;height:100%;width:auto;overflow:hidden;"
    ></div>
    <div
      class="bg-grey-darker"
      style="display:inline-block;height:100%;width:auto;overflow:hidden;"
    ></div>
    <div
      class="bg-grey-darker"
      style="display:inline-block;height:100%;width:auto;overflow:hidden;"
    ></div>
</div>

Scroll method above, was for debugging the following implementation, which was throwing same illegal invocation error.

scroll: task(function*() {
    yield this.get("scroller").scrollToElementId(...arguments);
  }),
...
this.get("scroll").perform(component.element.id, {
        duration: 50,
        easeType: "linear",
        padding: {
          x: 50,
          y: 50
        },
        axis: "x",
        container: "scrollable-in-viewport"
      });

Logger for this scenario yields:
{y: 0, x: 0} {y: 0, x: 3937} "tx:3887, ty:-50, ox:0, oy:0, xy"

and Illegal invocation is for the following line:

// scroll x and y axis
scrollTo(eases[index] * targetX * dirX + offsetX, eases[index] * targetY * dirY + offsetY);

Am I missing something in the docs on how to implement?

I'm seeing the same thing here, similar invocation.

ember-concurrency-scroll/addon/services/scroller.js

Lines 170 to 173 in 9126e2d

	return (x, y) => {
	container.scrollLeft = x;
	container.scrollTop = y;
	};

This is where it breaks. If you pass in the container as the third argument of that function instead of in the getScrollTo everything works properly.
