This guide aims to extend the main troubleshooting guide covering Replay-specific scenarios.

My canvas Elements Aren't Getting Captured

There's currently no support for canvas. It's being tracked in this GitHub issue. Feel free to 👍 and help us prioritize it.

My Custom CSS/Images/Fonts/Media Aren't Appearing When I View the Replay

The replay 'video' is actually a video-like reproduction of the HTML on your website. This means that all the external resources your site uses (CSS/Images/Fonts), will be rendered by the corresponding <style>, <img> and <video> tags on your site. Add to your CORS policy so the iframe hosted on can fetch and display these resources.

Replay on My Bowser Extension Doesn't Work

This is not a supported use-case. The replay package is built to work on a website and not as an externally-loaded script via browser extension or other mechanism. In fact, Sentry's Session Replay product can help developers find out when a third-party Chrome extension causes otherwise hard to debug or reproduce issues with their website.
