Hi, I get the following error when trying to update user details: No module named 'humanize'.
I just open the settings and press save without changing anything.
Any idea anyone?

#

which verison are you running?

lusty nymph
#

2026.2.1

stark jetty
#

Clean install or upgraded? Also is there any error in the server logs or the event log?

lusty nymph
#

Upgraded, this instance runs since 2024. Where can I find server logs? Event logs has a "Policy failed to execute" log

stark jetty
#

can you post that log event from the event logs?

#

I see now it comes from the avatar policy

#

is there no straightforward method to allow users upload their avatar?

#

I copied this policy from somewhere, but it appears to not work any longer

stark jetty
#

its just the usage of the humanize module in that policy, which we no longer include (it was never a direct dependency of ours, it got pulled in through another dependency)

#

whats the policy?

lusty nymph
#

the policy converts the selected file into a base64 representation and saves it in the user profile

stark jetty
#

sorry I meant whats the expression in the policy

change it to this

AK_DOMAIN = "authentik.company"
FILE_PATH = "/media/user-avatars/"
URL_PATH = f"https://sso.domain.org/{FILE_PATH}"
MAX_UPLOAD_SIZE = 5 * 1024 * 1024

      return False
    # Now we know it is one of the accepted image file types

    avatar_binary = b64decode(avatar_base64)

    avatar_overwritten = True
    remove_old_avatar_file()
    prompt_data["attributes"]["avatar"] = URL_PATH + avatar_filename

if "avatar_reset" in prompt_data.get("attributes", {}):
  del prompt_data["attributes"]["avatar_reset"]
  # If a new avatar was uploaded, previous avatar is deleted anyway, so ignore
  if not avatar_overwritten:
    prompt_data["attributes"]["avatar"] = None
    remove_old_avatar_file()
    ak_message("Deleted user avatar.")

return True
#

changes humanize to django.template.defaultfilters.filesizeformat which will always be there

lusty nymph
#

works, thank you! I dont quite understand why there is no built-in way of uploading an image to the authentik instance and use it in user attributes

stark jetty
#

file management used to be quite painful up until the recent file update, so now that thats in, we're definitely want an avatar system
