Seems to be a problem with a string primary key:

@Serializable
@Entity
data class ChoiceEntity(
    @PrimaryKey(autoGenerate = true) val id: Int,
    val fkParameter: Int
)


data class FullChoice(
    @Embedded val choice: ChoiceEntity,
    @Relation(
        parentColumn = "fkParameter",
        entityColumn = "id"
    )
    val parameter: ParameterEntity
)

Using the FullChoice in a dao leads to above mentioned problem if ParameterEntity.id is a string. If the id is an int everything works as expected.

Yes - A fix for this was recently submitted and will be in the next version of Room.
