    We are getting an error when using the mediaRecorder in Chrome browsers. I posted about this previously (thinking it was specific to print, but it is all recording with video). The console throws this error:

    – Uncaught TypeError: Cannot read properties of undefined (reading ‘call’) at e.onstart (PennController.js:40:142658)
    – PennController.js:40 Uncaught (in promise) DOMException: The play() request was interrupted by a new load request.

    The DOMException seems to be a Chrome-specific error. Everything works fine in Chrome if we record only audio; Both audio and vidoe work fine in Firefox.

    Thank you for the report. This is a known issue that appeared with the latest release of Chromium, affecting both Chrome and Edge. It seems that Firefox isn’t affected so far, but I can’t guarantee it’ll stay that way. I’m looking into the issue

    Apologies for the inconvenience,
