Problem with running migrations on startup

[SanderBreivik]

I have tried implementing migrations on startup. However, I get this error: System.InvalidCastException: 'Unable to cast object of type 'MongoDB.Bson.BsonDocument' to type 'MongoDB.Bson.BsonString'.' Stack trace:

  at MongoDB.Bson.BsonValue.get_AsString()
  at Mongo.Migration.Services.DocumentVersionService.GetVersionOrDefault(BsonDocument document)
  at Mongo.Migration.Migrations.Document.DocumentMigrationRunner.Run(Type type, BsonDocument document, DocumentVersion to)
  at Mongo.Migration.Migrations.Document.StartUpDocumentMigrationRunner.RunAll()
  at Mongo.Migration.Services.MigrationService.OnStartup()
  at Mongo.Migration.Services.MigrationService.Migrate()

  at Dialogue.Composer.Program.<>c__DisplayClass2_0.<CreateHost>b__0(HostBuilderContext context, IServiceCollection services) in C:\Dev\Microservices\Composer\Dialogue.Composer\Program.cs:line 118

What am I doing wrong here?

This is my init:

IMongoClient clientMongoDB = new MongoClient(databaseSettings.ConnectionString);

MongoMigrationClient.Initialize(clientMongoDB, new MongoMigrationSettings
{
    ConnectionString = databaseSettings.ConnectionString,
    Database = databaseSettings.DatabaseName
});
