Error messages - what do they mean

Hi, I get two error messages when loading workflows. It is the same error msg for all workflows so I guess it is a general errors. Does anyone recognize these and know how to fix it?

These are:

1: Method ‘AuthenticateAsync’ in type
'Microsoft.AspNetCore.Http.Authentication.Internal.DefaultAuthenticationManager1 from assembly ‘Microsoft.AspNetCore.Http, Version=2.2.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60’ does not have an implementation.

Log:

Hi @Evert_Randers ,
I think you can the temporary packages and try again.
Check at locations:
%USERPROFILE%.nuget
%LOCALAPPDATA%\UiPath.cache
%LOCALAPPDATA%\NuGet
%LOCALAPPDATA%\Temp\NuGetScratch
%LOCALAPPDATA%\Temp\nuget

regards,
LNV

Hi,

Thanks for you suggestion, but I did not find any useful files in those locations

@Evert_Randers , you can share your error when run robot?

@Evert_Randers

  1. Rename the project.json and reopen and check if that fixes
  2. Renames the packages folder in C:\users<username>.nuget and reopen the project …this downlods the pckages again and any missing references might be downloaded

Cheers

That worked, thanks!
