I have been trying to get a PDF to generate when the user clicks a button. I have a pdfGenerator.js and http-functions.js on the backend, and on the frontend I have code connected to the button the user will click to generate and download a PDF. When the page loads, the browser console gives the message "Rendering Environment: browser" Looking at the browser console once the button is clicked, I see the PDF was generated with the PDF Data URI, then a message saying Attempting to download PDF, and then the error message saying document is not defined. Ensure this code runs on the client-side. Since the environment is browser, isn't already client-side? Below is the frontend code that I currently have in place. The memory and fetch are being used to fill out text input fields on the page that is based of random number generators and CMS dataset tables on other pages. Code might look messy, sorry. Very new to coding and doing a 'learn as I go" approach. https://nabattrpg.wixsite.com/luminacity/character-form import { memory } from 'wix-storage'; import { fetch } from 'wix-fetch'; import wixWindow from 'wix-window'; $w.onReady(function () { if (wixWindow.rendering.env === 'browser') { console.log('Rendering environment:', wixWindow.rendering.env); $w("#button10").onClick(async () => { console.log('Button clicked, starting PDF generation process.'); const data = { // Character Childhood childhoodHomeDistrict: $w("#childhoodhomedistrict").value, parentsprofessions: $w("#parentsprofessions").value, pasteducation: $w("#pasteducation").value, majorchildhoodevent: $w("#majorchildhoodevent").value, // Character Past pastgangaffiliation: $w("#pastgangaffiliation").value, pastcorpaffiliation: $w("#pastcorpaffiliation").value, pastaddiction: $w("#pastaddiction").value, pastoccupation: $w("#pastoccupation").value, pastfamilymembers: $w("#pastfamilymembers").value, familyrelationship: $w("#familyrelationship").value, pastmajorrelationshiptrauma: $w("#pastmajorrelationshiptrauma").value, // Character Present presentfriends: $w("#presentfriends").value, presentfriendsrelationships: $w("#presentfriendsrelationships").value, presentenemiesperson: $w("#presentenemiesperson").value, presentenemiescause: $w("#presentenemiescause").value, presentenemiesbackup: $w("#presentenemiesbackup").value, presentenemiesconfrontation: $w("#presentenemiesconfrontation").value, presentromanticrelationship: $w("#presentromanticrelationship").value, presentlifegoals: $w("#presentlifegoals").value, debtamount: $w("#debtamount").value, debtcreditor: $w("#debtcreditor").value, familydeceasedmember: $w("#familydeceasedmember").value, familydeceasedcause: $w("#familydeceasedcause").value, familymembermissing: $w("#familymembermissing").value, currentoccupation: $w("#currentoccupation").value, // Character Personality personality: $w("#personality").value, personalityclothingstyle: $w("#personalityclothingstyle").value, personalityhairstyle: $w("#personalityhairstyle").value, personalitymostvalueditem: $w("#personalitymostvalueditem").value, personalitymostimportantvalue: $w("#personalitymostimportantvalue").value, personalitymostvaluedperson: $w("#personalitymostvaluedperson").value, personalityfeelingpeople: $w("#personalityfeelingpeople").value, personalityfavoriteband: $w("#personalityfavoriteband").value, customcampaignbg: $w("#customcampaignbg").value }; // Function to download the PDF function downloadPDF(pdfDataUri) { console.log('Attempting to download PDF.'); if (typeof window !== 'undefined' && typeof document !== 'undefined') { const link = document.createElement('a'); link.href = pdfDataUri; line.download = 'CharacterBackstory.pdf'; document.body.appendChild(link); link.click(); document.body.removeChild(link); } else { console.error('document is not defined.
