DocsTroubleshooting browser integration
Unable to spy elements on a web site
Using the browser extensions to automate web pages relies on a connection between the extension and Blue Prism. Situations where elements of a website cannot be spied can be improved by increasing the timeout between Blue Prism and the browser to allow sufficient time to make the connection.
To troubleshoot this:
- Navigate to the Blue Prism install location and open the Automate.exe configuration file in a text editor.
-
Increase the BrowserAutomation.DefaultCommunicationTimeout value.
The default value is 3000 milliseconds – the optimum value is dependent on the responsiveness of the browser.
- Relaunch the browser and navigate to the required website.
Browser automations should not be run by runtime resources with elevated permissions as this might affect the interaction with the application that is being automated. The permissions of the runtime resources must match those of the user context of the browser extension’s native messaging host (NMH).

The browser extension is not compatible with the Blue Prism version
Users are notified if the browser extension they are using is not compatible with their installed version of Blue Prism.
