Puppeteer to download file with Page.setDownloadBehavior

I am currently having issues downloading a file via URL. The download itself is working, but an incorrect extension of “.crdownload” is added to the end of the working extension.

Steps to reproduce

Environment:

• Puppeteer version: ^0.12.0

Steps:

const reportLink = await page.$('table.icwTable > tbody#myReportResults > tr:nth-child(1) > td:nth-child(2) > a'); await page._client.send('Page.setDownloadBehavior', {behavior: 'allow', downloadPath: './'}); await reportLink.click({ clickCount: 1, delay: 100 });

1. Select the download URL
2. Set download behavior with Chrome DevTools Protocol Viewer
3. Click the link to download

Ideally the file would be downloaded and the extension would be “.xls”.

Currently the file is being downloaded, but with a file extension of “.xls.crdownload”. If I delete “.crdownload” manually the file downloads correctly - how do I stop the extra “.crdownload” extension from being added.

I just set out to try if this bug occurred to me when trying to download .csv files. However, for me, it downloads just fine in headless and non-headless.

async function download(page) {
    await page._client.send('Page.setDownloadBehavior', {
        behavior: 'allow',
        downloadPath: './'
    });
    await page.goto(DOWNLOAD_URL);
    await page.click(DOWNLOAD_BUTTON_SELECTOR);
}

Using puppeteer ^0.13.0, working just fine. ✅

Hey guys, if it helps, what I noticed is that await page._client.send(‘Page.setDownloadBehavior’, {behavior: ‘allow’, downloadPath: ‘./’}); actually saved the file into the node_modules library where puppeteer/chromium was executing. So confirming what dallashuggins said: “…which downloads the file to a sibling folder on the same level as the file I am running (in the root directory).”

SO if you’re running puppeteer out of node_modules, then your path is relative to the puppeteer module directory:
