[🐛 Bug]:

[morettolss]

What happened?

I had a particular case, creating the file and calling the function at the same time it happened that the first file was overwritten by the second one that was being generated. The error does not seem to be reproducible in a standard way but only after X attempts.

How can we reproduce the issue?

print_settings = {
            "recentDestinations": [{
                "id": "Save as PDF",
                "origin": "local",
                "account": "",
            }],
            "selectedDestinationId": "Save as PDF",
            "version": 2,
            "isHeaderFooterEnabled": False,
            "isLandscapeEnabled": True
        }

        options = webdriver.ChromeOptions()

        driver = Chrome( options=options)

        driver.get("data:text/html;base64," + html_bs64)
        pdf_data = driver.execute_cdp_cmd("Page.printToPDF", print_settings)
        driver.quit()
        f = open(fname_dir, 'wb')
        f.write(base64.b64decode(pdf_data['data']))
        f.close()

to replicate the problem it's possible to add a time.sleep(1) after the pdf_data

        driver = Chrome( options=options)
        html_bs64 = base64.b64encode(body.encode('utf-8')).decode()
        driver.get("data:text/html;base64," + html_bs64)
        pdf_data = driver.execute_cdp_cmd("Page.printToPDF", print_settings)
        time.sleep(1)
        driver.quit()
        #print(pdf_data['data'])
        f = open(fname_dir, 'wb')
        f.write(base64.b64decode(pdf_data['data']))
        f.close()
