Designer: file:// Protocol Support
Issue
Appvance Designer does not support automating pages opened directly using the file:// protocol.
Solution
To automate a local HTML page with Designer, serve the page through a web server instead of opening it directly with the file:// protocol.
- Start a web server that serves the directory containing your HTML pages.
- Open the page using its HTTP or HTTPS URL, for example:
http://localhost:8080/index.html - Open the page in Designer using the web server URL.
- Create or run your automation against the page served through HTTP/HTTPS.
Note: Opening the page directly from the local file system using a URL such as
file:///C:/path/to/page.htmlis not supported for Designer automation.
