You can also try this:

await page.$eval('input[name="date"]', (el, value) => el.value = value, VARIABLE);

You can use page.type like so,

const VARIABLE = "01.01.2020"
await page.type('input[name=date]',VARIABLE);

You can refer to the thread for more info - https://github.com/puppeteer/puppeteer/blob/master/docs/api.md#pagetypeselector-text-options
