Steam Workshop Upload Problem

[SrJardel]

Hi.
 
I'm trying to upload a mod on Steam Workshop, but it fails every single time.
I'm suspecting theres something with files already in the cloud storage, as we can see in the startup log:

123

 
note the lines #4, #5 and #6.
 
It's weird the two variations of "preview" file, a .jpg one, and the other .png.
For sure I've tried to upload both formats in the process of trial/error, but why would they still stored in the cloud?
Along with that we can see there's already mod data stored as well (mod_publish_data_file.zip).
 
And this is what I get every time I try to upload the mod:

456

 
Am I missing something here?

 

[EDIT FOR SOLVED]: Yeah, for some reason the mod name and/or description were causing problems. I've changed both to "Test" and renamed them after the upload.
