我有一个问题。我怎样才能防止数据库重置（同步强制为真）后出现以下错误？
序列化数据库错误：类型“enum_coverLists_supportingDocument”已存在
以下是我的模型的外观：

export const SUPPORTING_DOCUMENT = {
    MEDIATION_FEES: 'MEDIATION_FEES',
    LEGAL_COUNSEL_FEES: 'LEGAL_COUNSEL_FEES',
    FILING_COMPLAINT: 'FILING_COMPLAINT'
};

export const TYPE = {
    BUDGET: 'BUDGET',
    QUANTITY: 'QUANTITY',
    UNLIMITED: 'UNLIMITED'
};

const coverList = function (sequelize, Sequelize) {
    const coverList = sequelize.define('coverList',
        {
            id: {
                primaryKey: true,
                type: Sequelize.UUID,
                defaultValue: Sequelize.UUIDV4
            },
            title: {
                type: Sequelize.STRING,
                allowNull: false
            },
            description: {
                type: Sequelize.STRING,
                allowNull: true
            },
            supportingDocument: {
                type: Sequelize.ARRAY(Sequelize.ENUM({
                    values: [...Object.values(SUPPORTING_DOCUMENT)]
                })),
                validate: {
                    isIn: [...Object.values(SUPPORTING_DOCUMENT)],
                },
                allowNull: true
            }, 
            type: {
                type: Sequelize.ENUM,
                values: Object.values(TYPE),
                validate: {
                    isIn: [Object.values(TYPE)],
                },
                allowNull: false
            }
        });
    return coverList;
};
export default coverList;

堆栈：

• Node.js
• PostgreSQL数据库
• 续写
