Projected fields are returned not decrypted

[Sammi89]

Hi guys, I'm using version 7.0.1 of mongoose-field-encryption. Trying to run a simple find query projecting some of the encryoted fields, the query results data are not decrypted automatically. Is this a desired behavior or an issue?
Thanks a lot.

@Sammi89 Can you provide some sample code please?

The plugin is quite well tested and you can see samples for plugin usage in the tests:

Sure! I'm working with NestJS. I'll write you an example:

@Schema({ timestamps: true })
export class User extends SoftDeletedContent<User> {
  @Prop({
    required: true,
    trim: true,
    maxLength: 50,
  })
  firstName: string;

  @Prop({
    required: true,
    trim: true,
    maxLength: 50,
  })
  lastName: string;

  @Prop({
    required: true,
    trim: true,
    maxLength: 255,
  })
  email: string;
}

export const UserSchema = SchemaFactory.createForClass(User);

UserSchema.plugin(fieldEncryption, {
  fields: ['email', 'firstName', 'lastName'],
  secret: config.secret,
  saltGenerator: config.saltGenerator,
});

const UserModel = model('User', UserSchema);
const users = await UserModel.find({}, [], { projection: { firstName: 1, lastName: 1 } })

Ah I see what you mean - you are using the projection feature.

Unfortunately, this plugin does not support this feature :(.
