Read psd issue

[ParfenenkovEdit]

Hi, Emil!
I want ro ask you how to handle errors when i'm trying to open files.
I faced next issues:
Paper bag.psd
https://drive.google.com/file/d/1_00LaNCuHvQuV3tFkLuPRcPYaBPm0Wam/view?usp=sharing
2025-07-24 17:04:15 [LayerMaskData]Expected either 0 or 2 padding bytes, got 10 instead
2025-07-24 17:04:15 [DecompressRLE]Size of compressed data is not what was expected. Expected: 75347 but got 32084521 instead

Process finished with exit code -1073740791 (0xC0000409)

White Mug.psd

RuntimeError: 2025-07-24 17:25:27 [SmartObjectWarp]Internal Error: Invalid descriptor type encountered. Full exception: 2025-07-24 17:25:27 [SmartObjectWarp]Invalid warp style received, expected 'warpCustom' or 'warpNone' but got 'warpCylinder'

Can it be handled in PSD files? Do you know the root cause of it?
For the second one should I use only warpCustom?

Thanks for raising the issue! I was able to trace down the failing read pretty quickly as I was missing an extra condition in the decoding of layers.

As for the warps, currently only regular photoshop warps are supported but not puppet warps which from the looks of it were applied to both of your files.

I dont have an exact timeline for when these warps will be in place but having extra data to test different permutations like yoi've provided helps massively :)

Right I've gotten around to the Paper bag.psd I've managed to fix the issue causing the failure to read (the other warning Expected either 0 or 2 padding bytes, got 10 instead can be ignored).

However, even after my fix the smart object layer turns white when roundtripping. This is because the embedded PSD doesn't seem to contain a global image data that we can access. Likely because its a nested smart object.

@EmilDohne Thanks for your response. We will take a look how to avoid nested smart objects in our flow
