Try ERPNext Buy Support Partners Foundation

Ascii codec can't decode byte 0xd0 in position

I’m getting this message and found the traceback in the web.log from frappe.


No clue as how else to solve it, I have tried the locale settings and no luck
Some posts suggest removing non UTF chars from my apps, but I have another instance of ERPNext v12 running perfectly well with them.

Frappe will load the website and allow me to enter my password and user, but then I get this.

So far my workaround (not a direct solution per se) involved creating a new server and restoring a backup.

I faced the similar issue.
Root cause: What I found was the locale was not installed and configured properly. For me I picked up ubuntu-minimal:18:04 over container which obviously doesn’t have many assumed packages.
Steps I took to resolve.

  • in bash within root or with sudo (if available)…
    apt clean && apt update && apt install -y locales
    locale-gen en_US.UTF-8 # for to be sure of locales available 
    dpkg-reconfigure locales
  • choose a UTF-8 locale. say: en_US.UTF-8, en_IN.UTF-8 (Indian EN), hi_IN.UTF-8 (hindi/India)
  • run locale command in bash and should not pop-up any error.
  • restart server/container(lxd/docker) whereever frappe app is installed.
    Hopefully now the issue should go away!
