I am currently trying to open an html file generated with pydeck in a Pyqt5 webview window. I can open it on my browser (firefox, if that’s relevant) and it works correctly. However, if I try to open it in pyqt5, a blank window will open and I get the following errors:
js: Uncaught SyntaxError: Unexpected token '='
js: Uncaught ReferenceError: createDeck is not defined
I do not get these errors in my browser.
I have also tried saving the resulting HTML to a string instead of a file and sending it directly to window.setHtml. The result is the same. I have used this same code to show other HTML files and it has worked correctly.
Here is the code I am using:
r.to_html("test2.html")
data = Path("test2.html").read_text(encoding="utf8")
app = QApplication(sys.argv + ["--no-sandbox"])
window = QWebEngineView()
window.setHtml(data)
window.resize(640,480)
window.show()
sys.exit(app.exec_())
Here is the generated HTML as well:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>pydeck</title>
