WriteRequestBatch example assumes that all attributes are of StringSet type

[konradkiss]

Hey guys. The current docs branch has a great example on using WriteRequestBatch to add an item. The problem is that the method used in the example - Item's fromArray- will assume each attribute to be a StringSet. This will end you with an exception when the type of ie. your hash key is not a StringSet (which is exactly the case in your PutItem example).

You should probably include a heads-up with this specific example and mention that the constructor of Item will take attributes in the (old) array format which has type definitions.

I'm not sure I if what you are saying is correct. Have you tested out what you are describing? Item::fromArray uses Attribute::factory to make intelligent guesses at what each attribute's type should be. Nothing in the example you are referring to should result in there being a StringSet. It's possible I might also be misunderstanding you.

I did test it. Every attribute had ["SS" => value], which I found weird. I traced it to the Attribute::factory call before going with a new Item(...), so I don't have more info on that.
I'll be happy to dive in deeper tomorrow. It was a simple data array that works great with PutItem otherwise. Regardless, I should get back to you in a few hours about what else I can find.

OK, we'll look into that too. Thanks for letting us know.

Jeremy, it looks like I'm not able to reproduce the problem I was having. I'm terribly sorry to have wasted your time. Everything works as designed and Attribute::factory assigns types as expected.

Hey, no worries! Thanks for looking back into it for us. 😄
