nil | amazingly awesome and reasonable null object implementation | Pub Sub library

There are a couple of things to try out and fix:

You probably don't need the many2many attribute to load the DonationDetail slice, since they can be loaded only with DonationID. If you have a foreign key, you can add it like this:

tl;dr: Try another set of images, probably there is something wrong with your set of images.

I've had it work successfully except in one instance, and I received the same error that you are getting. I think for some reason it didn't like the set of photos I took for that particular object. You could try taking just a few photos of another simple object and try again and see if that is the problem with your first run.

In ranges-v3, there is iterator_range which you can use to wrap the iterators into a range object.

In C++20, you can use std::span to wrap those iterators into an range object

Azure Cosmos db is only supporting Unicode or ASCII in x-ms-documentdb-partitionkey while github.com/vippsas/go-cosmosdb package is using json.Marshal which internally transforms Unicode to Chinese characters automatically.

The only way to solve it is using English as partition key when creating documents.

As Bhargav Rao deleted my previous answer, I will add a new one.

Users of external identity providers have to be registered before the can login.

You can find the details here: https://developers.tapkey.io/api/authentication/identity_providers/#working-with-users

When it is necessary for your use case, that these users are automatically created when they login, please send a request to tapkey support and they will enable this feature for you.

You can store them with a GADT, like this:

Here is one way to think about this problem. If the input is the empty list, then the result is (). If the input is a list containing a single list, then the result is just the result of mapping list over that list, i.e., (combinations '((1 2 3))) --> ((1) (2) (3)).

Otherwise the result can be formed by taking the first list in the input, and prepending each item from that list to all of the combinations found for the rest of the lists in the input. That is, (combinations '((1 2) (3 4))) can be found by prepending each element of (1 2) to each of the combinations in (combinations '((3 4))), which are ((3) (4)).

It seems natural to express this in two procedures. First, a combinations procedure:

The duplicate not being removed. Nothing prints

You print something in both branches of your conditional statement. If there is nothing printed that means the loop does not run a single time. That means that player.Backpack:GetChildren() returns an empty table.

As Instance:GetChildren() will always return a table, seeing an empty table means that Backpack does not have any children.
