Hi, I have following problem: the WebEmbed works when I develop the layout, but does not work when I publish the app. I’m trying to open a FLOWISE agent. Any idea why it does not work?

Are you using a URL to embed, or do they provide an embed code for you?

I am using an URL.

I found the issue: Flowise has recently added security features and I need to allow the published glide app (not the Glide development environment) in there, by adding it to the CORS\_ORIGINS and IFRAME\_ORIGINS. Maybe Glide should update their information to suggest that users check these variables when they connect URLs.

So after updating it on the Flowise side, you can now embed it in Glide’s production version? Thanks for sharing.
