Puppeteer: Must start a new Touch first

A touch move/end operation has no started touch to act on.

Error message

Must start a new Touch first

A touch move or end operation requires an active touch. Calling touchMove on a fresh touchscreen has no touch to move.

The snippets use an open Puppeteer page named page.

await page.touchscreen.touchMove(
    100,
    100
);

Start the touch, move it, then end it.

await page.touchscreen.touchStart(
    50,
    50
);

await page.touchscreen.touchMove(
    100,
    100
);

await page.touchscreen.touchEnd();

Use touchscreen.tap for a complete tap. A viewport with touch support may be needed for the application to respond as a touch interface.
