I can't upload mod to the Steam Workshop

[Renday Walter]

When I try to upload my mod to Steam Workshop using "Don't Starve Mod Uploader" I get error message:

Something went wrong while publishing your mod!

Error: Failed sharing mod data file.

The mod itself tested for performance in the game, it works fine and does not throw any errors, I also tried to use a different picture, but it did not solve my problem, the error message still appears. OS: Windows 10 Pro 1903 x64. Running Steam as Administrator gives the same result. What else can I do to make this program finally upload my mod to the Workshop? And sorry for my bad english.

Check your Don't Starve Mod Tools log file. Aside from that, we can't help unless we at least see your mod. Please zip it and attach it to a reply here.
