First off, thanks for the work on the SDK - I realize this is a work in progress but since this behavior is new, I thought I'd ask anyway.

I started seeing HTTP responses 422 every time my app tries to create a new folder. The code is nothing special:

await this.client.createFolder(parentId.uid, name, new Date());

The same code was working two days ago, now it seems to be failing consistently with

ProtonApiError: Could not verify the nodeKey was used for encrypting xAttr, nodeHashKey

This feels like a server-side change since the same is now happening for older versions of the SDK as well - tested with 0.10.0. It's also happening on two different Proton accounts. Additionally, a similar error happens when I try to upload a file:

Could not verify the nodeKey was used for encrypting , contentKeyPacket

My question is: is this a user error, something that can be fixed with the current SDK or is a breaking change that requires a new SDK version to be published? Any additional information would be greatly appreciated.

Our web client with the SDK is working properly. We are not aware of any breaking change that would cause this. Very likely the problem is in the integration part with the crypto or account dependencies, for which we do not provide support yet. Our guess is that the time feeded to the crypto library is off causing the issues.
