Vantage Scope: Could not load type 'Abbyy.Integration.Vantage.Shared.PublicApi.GrantType' from assembly 'Abbyy.Integration.Vantage.Shared.PublicApi, Version=1.2.0.0, Culture=neutral, PublicKeyToken=null'.

Cause

The issue may be caused by the connector's packages, which were not upgraded in the project dependencies after the new version of the connector was installed.

Resolution

When installing the new version of the Vantage Connector for UiPath, it is necessary to also add the new activities from the package in the dependencies. For this, the following steps need to be performed:

   folder to your package source folder. The NuGet packages are located in the UiPath Activities
   subfolder of the installation folder that was created during the connector installation (the default location is C:\Program Files\ABBYY Vantage Connector for UiPath\UiPath Activities). After the NuGet connector packages are added to the available package source, you can install the connector package to the project dependencies.

   1. Click on the newly created package source category.
