Bug Description

Mysql not insert 0 to column

In 500 record, but 20 record not work

Model:

access_d: {
  type: DataTypes.STRING(2),
  allowNull: false,
  primaryKey: true,
  comment: "日"
},

Nodejs code:

_data = {
  access_d: "01" // Error from 01 - 09
};
logger.debug("Insert data:", _data)
return db[_table].create(_data, {
  transaction: tx
});

SQL log

{"timestamp":"2021/12/09 10:04:07.818","type":"sql","level":"verbose","message":"eUsTc Executing (f3b0a8cd-e596-4e33-b220-84e4a57f4676): INSERT INTO `table name` (`access_ym`,`access_d`) VALUES (?,?);"}

Create method is worked, i'm insert debug code befor create method. Create data no problem.
But i got wrong data on database

How to debug it ? :(
