Problem with running process on the production machine

When I try to run process from production machine, I get error

“C:\Users\evaprod\Desktop>“C:\Program Files (x86)\UiPath\Studio\UiRobot.exe” -file “C:\Robot\PlasiraniSaldirani\lib\net45\Main.xaml” /executor /monitored
The feed ‘Official [https://www.myget.org/F/workflow/]’ lists package ‘System.Buffers.4.5.0’ but multiple attempts to download the nupkg have failed. The feed is either invalid or required packages were removed while the current operation was in progress. Verify the package exists on the feed and try again.”

I have to nitice that everything was OK while running it on the Uipath DEV server.

Does anyone have an idea what is the problem in this case?

@Olivera_Kalinic,

You may not have internet access in the PROD machine to download the package. Copy the package from your DEV machine to the PROD machine, then try once.

But I don’t know what package is making problem. Should I copy all packages?
And to what location? Maybe I am doing something wrong…

Are yiu using any custom packages? System.Buffers?

No, I don’t even know what System.Buffers is :).
It’s the first time this error appears.

I tryed again and I get the error below

"

Would you change the package versions manually in the project.json file (copied from a running project file) and reopen the project.

But how to change it? I don’t know why this version of package from the error above is incorrect…
The same version is on the DEV enviroment, too, and it works correctly…

I have access to internet from the PROD machine, that is not problem for sure. Also I’ve copied all packages from DEV to PROD and it doesn’t work :frowning:

@Olivera_Kalinic,

What error you are getting, possible share that here.

This is the error I’m getting:

“The feed ‘Official [https://www.myget.org/F/workflow/]’ lists package ‘System.Memory.4.5.3’ but multiple attempts to download the nupkg have failed. The feed is either invalid or required packages were removed while the current operation was in progress. Verify the package exists on the feed and try again.”

Any suggestion, please?

@Olivera_Kalinic ,

Check whether this package is there or not in the PROD machine. If it is there then in your DEV machine uninstall it and reinstall the latest version of this package. Else in the same production machine check with a different user account for the same process and package.
