//Structure of the class Info

{
     public IList<string> Type { get; set; }
     public IList<string> Flow { get; set; }
}

//Trying to convert the returned result into dictionary
db.InsertMissingInfo(result.Item1.ToDictionary(k => k.Key, v => new Info { Type = v.Value.Type, Flow = v.Value.Flow  }));

You could use the coalesce operator:

db.InsertMissingInfo(result.Item1.ToDictionary(k => k.Key, v => new Info { Type = v.Value.Type, Flow = v.Value.Flow ?? new List<string>()  }));
