Help me please. I created a mod but I can't publish it

The problem is that when loading the mod, 3 errors appear depending on the actions. 1 error - File not open: C:\Users\A...\Documents\My Games\Terraria\tModLoader\Mods\MoreArtifacts.tmod 2 error - Failed to publish the item to steam! Did you modify the game's steam application ID? 3 error - Failed to publish the item to steam! Error Code: K_EResultRateLimitExceeded And often a dummy appears on Steam, there are screenshots (I already have 1 mod loaded, it's small, only 3 items)
