Missing or Invalid Activity on UIPATH studio version 2020.10.10

Hi , I created automation in Latest Updated version and after that degraded the packages . After degradation getting error “Missing or Invalid Activity”.


Hi @ankush.jeengar

Welcome to uipath community

Why are you downgrade the package. Try to work on latest package.

This generally happens when you built a workflow using a specific versions of Project Dependencies & then upgrade or degrade the activities package (Most of the time it works) / downgrade the activities package (Generally Never Works). Please make sure you use the recommended versions of activity packages.

Have a look on docs

You may try to set back the previous package version or create the automation again in the actual version.

Actually , I want to work on downgrade package, will create automation again.
Thanks @marian.platonov @Gokul001
