Roomigrant: java.lang.IllegalStateException: Migration didn't properly handle:

Room Version: 2.2.5 Roomigrant Version: 0.34

I just removed a single property from my entity class and then got this error message:

Before

@Parcelize
@TypeConverters(Converters::class)
@Entity(tableName = "customers")
data class EntityCustomer(

    @PrimaryKey
    @ColumnInfo(name = "uuid")
    val uuid: String = UUID.randomUUID().toString(),

    @ColumnInfo(name = "priority")
    var priority: Int = 1,

    @ColumnInfo(name = "is_manually_scheduled")
    val isManuallyScheduled: Boolean = false,

    @ColumnInfo(name = "is_deleted")
    val isDeleted: Boolean = false,

    @ColumnInfo(name = "owner")
    val owner: String = "undefined"
) : Parcelable

After

@Parcelize
@TypeConverters(Converters::class)
@Entity(tableName = "customers")
data class EntityCustomer(

    @PrimaryKey
    @ColumnInfo(name = "uuid")
    val uuid: String = UUID.randomUUID().toString(),

    @ColumnInfo(name = "priority")
    var priority: Int = 1,

    @ColumnInfo(name = "is_manually_scheduled")
    val isManuallyScheduled: Boolean = false,

    @ColumnInfo(name = "is_deleted")
    val isDeleted: Boolean = false,
) : Parcelable

Im planning to go production soon but I am not sure about using this library, especially if I’m making bigger changes to the schema. I don’t want the app to crash on startup.
