We are facing an issue where a Sequence workflow works correctly, but both existing and newly created REFramework projects throw the following error when interacting with websites:
“Unable to communicate with the browser.”
The issue occurs with all selectors. We have already reinstalled the UiPath Chrome extension, but the problem persists.
Has anyone experienced this issue or found a solution? Any suggestions would be greatly appreciated.
This error is usually related to the communication between UiPath and the browser rather than the REFramework itself. Since your Sequence workflow works but REFramework projects don’t, here are a few things to check:
Verify whether the issue occurs immediately after opening the browser or only during a specific activity.
Ensure the browser is launched by the same UiPath process/session that’s attempting to automate it. If the browser is already open, try closing all browser instances and let UiPath launch a fresh one. Else, use a Kill Process activity to let UiPath open the fresh browser.
Confirm that the Chrome extension is enabled in Chrome (chrome://extensions) and that the installed extension version is compatible with your UiPath Studio/Robot version.
Check if you have enabled Allow Private option in the Use Application/Browser. If yes, then you need to enable the Allow in InPrivate option in the UiPath Browser Automation extension.
Please check the above options and let us know if you are still facing the issue.
