Prepared insert statement with customType

When using prepared insert statement with customType the Placeholder object gets passed to the toDriver of the custom type. How do I resolve it? Schema:

export const sessionSchema = pgTable('session', {
  id: bigintString('id', { mode: 'bigint' }).primaryKey().$default(() => generateSnowflake()),
  // More fields
});

export const sessionSchema = pgTable('session', {
  id: bigintString('id', { mode: 'bigint' }).primaryKey().$default(() => generateSnowflake()),
  // More fields
});

The custom type:

export const bigintString = customType<{
  data: string;
  driverData: bigint;
}>({
  dataType: () => 'bigint',
  toDriver: (value) => {
    return BigInt(value);
  },
  fromDriver: (value) => {
    return String(value);
  },
});

export const bigintString = customType<{
  data: string;
  driverData: bigint;
}>({
  dataType: () => 'bigint',
  toDriver: (value) => {
    return BigInt(value);
  },
  fromDriver: (value) => {
    return String(value);
  },
});

Prepared statement:

public static readonly preparedUpsertStatement = db
    .insert(sessionSchema)
    .values({
      id: sql.placeholder('id'),
      // More fields
    })
    .onConflictDoUpdate({
      target: sessionSchema.id,
      set: {
        // More fields
      },
    })
    .returning()
    .prepare('session_upsert');

public static readonly preparedUpsertStatement = db
    .insert(sessionSchema)
    .values({
      id: sql.placeholder('id'),
      // More fields
    })
    .onConflictDoUpdate({
      target: sessionSchema.id,
      set: {
        // More fields
      },
    })
    .returning()
    .prepare('session_upsert');

What gets passed to the toDriver of the custom type:

Placeholder {name: 'id'}
name:
'id'
[[Prototype]]:
Object
constructor:
class Placeholder {\n  constructor(name2) {\n    this.name = name2;\n  }\n  static [entityKind] = "Placeholder";\n  getSQL() {\n    return new SQL([this]);\n  }\n}
getSQL:
ƒ getSQL() {\n    return new SQL([this]);\n  }
[[Prototype]]:
Object

Placeholder {name: 'id'}
name:
'id'
[[Prototype]]:
Object
constructor:
class Placeholder {\n  constructor(name2) {\n    this.name = name2;\n  }\n  static [entityKind] = "Placeholder";\n  getSQL() {\n    return new SQL([this]);\n  }\n}
getSQL:
ƒ getSQL() {\n    return new SQL([this]);\n  }
[[Prototype]]:
Object
