Cannot Create Unknown Type activity Read Cell URGENT

Help

Hi, i am currently an intern in a company and i really need urgent help for this. The UiPath i am using is an Enterprise Edition 2018.2.2. It actually works fine when i run it manually on the Studio itself but when i schedule to run it using Windows Task Scheduler the robot app only appears for a split second and it closed without anything happened although it showed Task Run Successfully. I actually managed to screen capture the robot during that split second and it showed this:

I searched about this error here in UiForum there are quite many similar experiences to mine, tried the solutions provided but still nothing seems to workā€¦

  • Tried install and uninstall the activities
  • Already press publish at least once to have the project.json file
  • Refreshing the computer

And why do the previous processes all still working fine? There are about 10 UiPath processes scheduled in the Task Scheduler that run daily/weekly/monthly and all seems to work flawlessly. When i add new process then its showing me this!
I really hope someone can help me with this as my intern period is ending soon and i need to make this work!!

Buddy @AinMM

To get past this, go to package manager and install package
UiPath.Framework.Activities
UiPath.Core.Activities
Close Studio, Open Studio and run again buddy, in the new process

this can give you more view on it

the reason is the read cell activity s getting failed in your process, see the secondline in the error screenshot buddy(the left end in second line)

Hey @AinMM

Schedule Task feature is deprecated and no longer supported.
Using UiPath Orchestrator is recommended.

NOTE - When i Tested with 2018.4.1 it was working like before.

Hey @AinMM

Mate i was just asking you to take steps in windows task scheduler :slight_smile: because if you will see that earlier feature was having task scheduler window only :stuck_out_tongue:

anyway follow this :slight_smile: Scheduling a back office robot using task scheduler - #13 by acaciomelo

Hi @aksh1yadav , sorry tried it and still not working. Hmmm

The activities exist in this two folder must it be the same?
%LocalAppData%\UiPath\Activities
and
%USERPROFILE%.nuget\Packages

I am still trying to figure out why it says ā€œCannot Create Unknown Typeā€¦ā€ when all the activities needed are already installedā€¦

Hi @AinMM

The feed for the robot activities is different than the one for local Studio activities. What is probably happening is that the robot is trying to download activities from specific feeds but is blocked by the firewall.
See here for detailed description for your version:

I could see two solutions here - either copy paste the files from the Studio feed to the Robot feed manually, or unlock the feeds in the firewall.
