Hello, being new to Katalon (v7.0.7 on Mac) I used ‘record web’ to automate login to a web site and download a PDF from the site, which worked well. Executing the test case works well both with Firefox and Chrome. BUT: When I try to run the test case using a headless browser (both Chrome and FF), the PDF is not written to disk. Any idea what is wrong? Best regards, Michael ---

Hi @michael.seyfried It’s hard to say, can you post the relevant console log ? How are you downloading the PDF ? Are you clicking on a button, or using code ? ---
