So the generator in the mapper can also be removed ?

Internal Server Error\nAn exception occurred while executing a query: SQLSTATE[HY000]: General error: 1364 Field 'id' doesn't have a default value

Something seems off in the update case

[nickvergessen]

Internal Server Error\nOC\Snowflake\SnowflakeDecoder::decode(): Argument #1 ($snowflakeId) must be of type string, int given, called in …/lib/public/AppFramework/Db/SnowflakeAwareEntity.php on line 53 in file '…/lib/private/Snowflake/SnowflakeDecoder.php' line 26

Reading also fails.

Will have a look

Had to drop the createdAt column now as it is overlayed with the getCreatedAt from snowflake entity which also returned a different data type.
