log.verbose('PuppetPuppeteerBridge', 'initPage()')
// set this in time because the following callbacks
// might be called before initPage() return.
const page = this.page = await browser.newPage()
page.on('error', e => this.emit('error', e))
page.on('dialog', this.onDialog.bind(this))
const cookieList = (await this.options.profile.get('cookies')) as Cookie[]
const url = this.entryUrl(cookieList)
log.verbose('PuppetPuppeteerBridge', 'initPage() before page.goto(url)')
await page.goto(url) // Does this related to(?) the CI Error: exception: Navigation Timeout Exceeded: 30000ms exceeded
log.verbose('PuppetPuppeteerBridge', 'initPage() after page.goto(url)')
if (cookieList && cookieList.length) {
await page.setCookie(...cookieList)
log.silly('PuppetPuppeteerBridge', 'initPage() page.setCookie() %s cookies set back', cookieList.length)
}
page.on('load', () => this.emit('load', page))
await page.reload() // reload page to make effect of the new cookie.
return page
