Puppeteer: Touch has already started

A touch handle is started again while it is already active.

Error message

Touch has already started

How this error happens

A TouchHandle has a start/end lifecycle. Restarting the same active handle repeats its start operation.

The snippets use an open Puppeteer page named page.

const touch = await page.touchscreen.touchStart(
    50,
    50
);

await touch.start();

How to fix

Move and end the active touch. To make another gesture, create a new touch after ending the first.

const touch = await page.touchscreen.touchStart(
    50,
    50
);

await touch.move(
    100,
    100
);

await touch.end();

Things to keep in mind

Run these as alternative sequences from a fresh touch state. Calling touchStart again can create a separate touch; it does not restart the existing handle.
