ToOne need to use converter?

[soroksorok]

Hi all,

Disclaimer, this is my first time using ObjectBox

Im trying to use relation

@Entity
data class Customer(
        @Id var id: Long = 0
) {    
    @Backlink(to = "customer")
    lateinit var orders: ToMany<Order>
}

@Entity
data class Order(
        @Id var id: Long = 0,
        var name: String? = ""
) {
    lateinit var customer: ToOne<Customer>
}

From the above classes, Im getting error as below
Cannot figure out how to save this field into database. You can consider adding a type converter for it.

Not sure if I did this correctly or not, need help figuring out why its saying this.
Do I actually need converter for using ToOne?

Thanks in advance. Btw great project

Thanks for reporting. However, this error message is not familiar. This should work without issue, assuming your code imports the ToOne class from the io.objectbox package.

Can you share the exact error message? Also, are you using the latest version of ObjectBox? If not, which one?

If possible supply the following info:

**Basic info (please complete the following information):**
 - ObjectBox version (are you using the latest version?): [e.g. 2.7.0]
 - Reproducibility: [e.g. occurred once only | occasionally without visible pattern | always]
 - Device: [e.g. Galaxy S20]
 - OS: [e.g. Android 10]
