Create customer endpoint returns 400 for emails with capital letters

Cloud

I had a customer email that I failed to create a token for with the create customer endpoint. I was looking for anything that was incorrect on my end, but I couldn't find anything obviously out of place. However, I did notice that the associated email address that was failing had capital letters in it, whereas the 900+ other customer emails we have all seem to be lowercase. Is it possible that this is the issue?

The below is the return from the endpoint,

ok: false, code: 400, error: "Requested customer scope doesn't exist"

If this is the issue I could of course ensure emails are lowercased before I send them to the cloud API, but just wanted to understand if this was an intentional limitation first.

I'm now seeing this about the same issue so I'll just go ahead and update things on my end to ensure emails are lowercase, though it would be nice to know which other endpoints also have this limitation.
