First There is my error: https://pastebin.com/EKiACCKR
After a few test to try solve that, I deleted Uchat and DeluxeTags and Vault, to reset config, still have the problem. So i decided to turn off plugins One By one to looks where it come from, after disable Vault, the error was gone. Si i try some other Vault plugins ( Maybe that one was broken) but still have that error even wioth differents Vault plugins.
If Someone know the source i will be gratefull.
