Converting drizzle custom type to Postgres composite type fails for arrays

type BeneficiaryAccountSqlValue = [
    account_number: string,
    beneficiary_name: string,
    bank_id: BankId,
];
export const beneficiaryAccount = customType<{
    data: BeneficiaryAccount;
    driverData: BeneficiaryAccountSqlValue;
}>({
    dataType() {
        return 'payment_config.beneficiary_account';
    },
    toDriver({
        accountNumber,
        beneficiaryName,
        bankId,
    }: BeneficiaryAccount): SQL<BeneficiaryAccountSqlValue> {
        return sql<BeneficiaryAccountSqlValue>`(${accountNumber},${beneficiaryName},${bankId})`;
    },
});

insert into ___ (..., "allowed_beneficiaries", ...) values (default, $1, $2, $3, $4, default, default, default, default, default, default) -- params: [true, "100.00", "200.00", "{[object Object]}"]
