This page renders to a canvas
Resolve the canvas_only_app scan error and understand when to start a new scan.

Why this happens
Almost all of the visible content is drawn into a <canvas> element, which has no accessibility tree for automation to inspect. This is a real limitation, not a scanner bug.
What to do
- Canvas-rendered apps need a manual audit. See our limitations page.
- Confirm that the target page and login method match the project you selected.
- After correcting the cause, start a new scan. Keep the original scan ID if you need support.
Before you retry
Repeating the same request without changing the cause may produce the same result. Never share credentials, session files, or sensitive screenshots in a support request.
