How to insert an ObjectId into a document in mongo and golang

I'm having a problem inserting an ObjectId into a doc.

this is the collection sale model

type Sale struct {
    ID      primitive.ObjectID   `bson:"_id,omitempty"`
    Client  primitive.ObjectID   `bson:"client"`
    Items   []primitive.ObjectID `bson:"items"`
    Amounts []int                `bson:"amounts"`
    Cost    float64              `bson:"cost"`
    Payment bool                 `bson:"payment"`
    Date    time.Time            `bson:"date"`
}

before generating the insert I ensured that Sale.Client has a valid ObjectId value, but when I perform this insert the value becomes binary within the table.

ex: ObjectId('67103588b9138d78d5ef09a2') Binary.createFromBase64('ZxA1iLkTjXjV7wmi', 0)

this is the insert code

func CommonInsert(collection string, ctx context.Context, model interface{}) error {
    conn, err := config.GetDbConnection(ctx)
    if err != nil {
        return err
    }

    c := conn.Database("teste").Collection(collection)

    _, err = c.InsertOne(ctx, model)
    if err != nil {
        return err
    }

    return nil
}

I generated real mock data for the insert and I still couldn't force the data to be transformed into ObjectId

Usually when a primitive.ObjectID is not being recognized as a MongoDB ObjectId type (but rather an ordinary byte array which is the underlying type of primitive.ObjectID), it boils down to:

• either you actually using a custom type (having primitive.ObjectID as its underlying type) such as type MyID primitive.ObjectID instead of primitive.ObjectID exactly
• or you mixing major driver versions

Currently there is a beta v2 major version of the driver, and there is of course the v1. Make sure you don't mix the 2 major versions: either use v1 or beta v2 everywhere.
