Hi @Partha_Maity

Welcome to our UiPath Forum! :slight_smile:

Could you try going to the package manager and updating the activity packages to the latest version (especially the System and UIAutomation ones)?


I am having the save pb. How do you know which specific activity package to update? There are multiple.

Typically, the System package and the UIAutomation package are the closest to Studio itself and will often fix the issues with new features.

Therefore, I would suggest trying to update these two first and see if it will fix the issue.

Also, we would appreciate a list of steps that lead to this error. We are trying to find the reliable reproduce steps for this bug to be able to fix it :slight_smile:

Will update in a second. It could just be that the packages needed updating because I follow step by the step the “for each” automation practice sequence for the “min & max”.

Thank you!

Hi @Partha_Maity

Could you try to perform a clean installation of your UiPath Studio?

Please refer to this topic:
How to fix your Studio installation / Licensing issues

Hi @Partha_Maity and everyone,

This should be fixed in the upcoming Community Edition 20.6 :slight_smile:
