Both name and value must be non-empty strings.

Error message

Both name and value must be non-empty strings.

What it means

The internal NameValuePair(string name, string value) constructor guards against null or empty strings for either the name or the value, throwing ArgumentException. It fires when a named value is created for the Task Scheduler v2 collection with blank data, since ITaskNamedValuePair requires both parts non-empty.

Solutions

1. Validate that both name and value are non-empty (string.IsNullOrEmpty) before constructing NameValuePair.
2. Skip or log entries that lack a name or value rather than adding them to the collection.
3. Substitute a meaningful placeholder value when real data may be empty.
