webview failed with error

When I tried to open a floating webview with simple code from official document Basic Setup · GitBook

It tries to open the webview but failed, then it shows a page in browser like below with URL https://bridge_loaded/

I am using BetterTouchTool version 3.506. I remember floating webview worked for me with this version recently. Not sure why it doesn't work now.

Can you check if there is anything wrong?

Weird, could you check whether this also happens in the latest alpha? (I can't seem to reproduce it here).

yes, I updated it to alpha version 3.538 and have the same issue.

I deleted the existing trigger with the webview and create a new one, then it works.
