When I run it in a browser it successfully downloads the file. (This is a small test wacz as a proof of concept before I start playing with 36G wacz files).
When I run it in Replayweb.page it errors out:
Sounds like a classic case of CORS errors! I don’t believe Dropbox allows users to use it to host embedded web content in this way. I know you’ve already solved this in your other thread with S3, but figured I’d confirm here anyways. For future reference, check out the Configuring CORS section of our docs.
This is expected. CORS applies to websites with domains and when the app is running locally it isn’t either of those
Actually, I finally got it to work from Dropbox with replayweb.page on the web in Firefox and Chrome… got this answer from the Github site: Configuring Server CORS | ReplayWeb.Page
