NuGet Dependecy Trigger

Trying to use the NuGet Dependency Trigger, but have problems getting it to work.

Got the following error message

Problem with NuGet Dependency Trigger

Under details the following message appears:

Failed to check for package versions. Value cannot be null.
Parameter name: property

The stacktrace is as follows:

When filling the details for the Trigger I did left the Package version field empty as it said that if it left empty the latest version should

"Specify package version to check. Leave empty to check for latest version"
