Known issues specific to MV3 extensions
javascript:
URI.
In this case, the simulated click will not take effect and no errors will reported.
This was reported as a Chromium bug. This issue is quite rare as very few HTML elements have click handlers in this form.
Workarounds
Two workarounds are available for this issue:
- Identify the failing Click activity in your workflow and change the input method from Simulate to any other input method (Chromium API, Hardware Events, Window Messages).
- Upgrade to UiPath.UIAutomation.Activities package v22.12 or newer and use the Enable workaround for simulate click with MV3 extension option in Project Settings.
The DeveloperToolsAvailability has the following possible values:
- 0 = Disallow usage of the Developer Tools on extensions installed by enterprise policy, allow usage of the Developer Tools in other contexts
- 1 = Allow usage of the Developer Tools
- 2 = Disallow usage of the Developer Tools
1
to
enable the full functionality of the extension.
This value is automatically set correctly when the extension is installed but it will be overwritten if your system administrator has set another value for this policy.
The other values for DeveloperToolsAvailability cause the problems listed below.
0
then:
- The UiPath Extension for Chrome v22.4 will not work at all with this restriction. Please consider upgrading to the v22.10 of the extension available with UiPathStudio.msi 2022.4.4.
- The UiPath Extension for Chrome v22.10 will be restricting to working with LTS versions of UiAutomation (19.10.x, 20.10.x, 21.10.x, 22.4.x)
- The
InjectJS
Activity will not work.
2
then:
- All the limitations from
DeveloperToolsAvailability=0
apply - The
ChromiumAPI
input method will not work.
ChromeNativeMessaging.exe
could not be started: Cannot
communicate with UiPath Platform The native part of the extension is not
configured correctly.
Re-install the extension from UiPath Studio.
jQuery $
, or to interact with page code (e.g.,
window.alert
). The Inject Js Script activity won't
report an error, but the script will fail to execute and the following error will be
reported in the browser DevTools (F12): Refused to execute inline script
because it violates the following Content Security Policy
directive
.
This is a limitation introduced by the MV3 platform.
To fix this issue, select the Execution world - Page option from the Inject Js Script activity.
This property is available starting with UiPath.UIAutomation.Activities v22.12.0-preview.
Your existing JavaScript code doesn't require any changes, and by using the Execution world - Page option it will work for both MV2 and MV3 extensions.
For MV3 extensions, the browser loads the extension later, after the web pages have loaded. This means that on slower machines, the Open Browser activity from UiPath.UiAutomation.Activities version 22.10 or older can reach the internal timeout of 20 seconds before the extension has started.
Starting with v22.12.0-preview, the internal timeout for the Open Browser activity has been increased from 20 seconds to 60 seconds.
Since you may need to set a longer timeout for the browser startup, it is now configurable from the Use Application/Browser and Open Browser activities. The following project settings have been added:
-
UI Automation Classic → Browser → Open browser timeout (seconds)
-
UI Automation Modern → Application/Browser → Open browser timeout (seconds)
UIPATH_OPEN_BROWSER_TIMEOUT_SECONDS
environment variable. For
example, set UIPATH_OPEN_BROWSER_TIMEOUT_SECONDS=120
to use 120
seconds for the activity's timeout.
- Click activity with Simulate fails on specific web page elements
- The DeveloperToolsAvailability Group Policy value must be set to 1
- The UiPath Web Automation browser window shows a warning
- The Inject Js Script activity can no longer be used to access page variables and code
- Open Browser activity has an insufficient timeout
