Skin (forced_to_be.wsz) fails to parse

[msikma]

Just happened to notice this tweet with a neat skin. Clicked through to try it out and got a "failed to parse skin" error.

I've attached the skin file.

Interesting. The error I get is:

Error: End of data reached (data length = 226274, asked index = 234498). Corrupted zip ?

When I try to unzip at the CLI I get:

I wonder how we were able to take the screenshot in the first place...

I'm afraid that might be my fault, somehow? I downloaded the wsz and zipped it myself using The Unarchiver on OSX. However, it seems to be unzipping fine for me. md5sum of the files:

2e146de10eef96773ea222fefad52eeb  2e146de10eef96773ea222fefad52eeb.wsz
862a6420e9d72f86d7c3dc0f702998d3  2e146de10eef96773ea222fefad52eeb.wsz.zip

The unzipped sha1sum is the exact same as for the file when I directly download it from the link in the tweet. Could it be that your download of the Github attachment failed?

Looks like you zipped the wsz and uploaded here, but I am getting that error when trying to unzip the actual wsz as well.

If you rename the .wsz to .zip and unzip that does it work?

[msikma]

Ah, no, you are correct. I didn't know .wsz files are actually zip files. I get precisely the same error as you do, down to the byte.

Maybe it's the upload/mirroring to AWS that failed?

[captbaritone]

I suspect that the archive is corrupt. I get the same error downloading directly from AWS: https://cdn.webampskins.org/skins/2e146de10eef96773ea222fefad52eeb.wsz

I don't think the file got corrupted during upload since the md5 of the file I download still works. I would say the file is just corrupt, except for the fact that we apparently generated a screenshot for it at some point.
