Error message uploading custom emoji

[jonpincus]

Describe the bug
Most of the time (although not always) I get an error message when trying to upload custom emoji. The new emoji briefly shows up, but then a flash message appears and and it vanishes from the list.

For the person who originally reported it, the emoji wasn't available at that point; when I tried to reproduce it, however, the emoji was available, and if I refreshed the list of custom emoji it was there. So it's possible there are two bugs here and I was only reproducing the first one. (

The flash error message says

Sorry, the function handle_event (overridable 1)/3 in module Elixir.Bonfire.UI.Me.SettingsLive didn't receive the data it was expecting -

The server log also has
Elixir.FunctionClauseError: no function clause matching in Bonfire.UI.Me.SettingsLive."handle_event (overridable 1)"/3

To Reproduce
Steps to reproduce the behavior:

1. Go to Settings
2. Click on Advanced / Custom Emoji
3. Fill in the lable and shortcode, and select a .png file

Expected behavior
The custom emoji should appear in the list (and I shouldn't get any error messages).

Bonfire environment (please complete the following information):

• Running env: prod
• Running with Co-op Cloud and/or Docker?: Co-op Cloud
• Running version (check on your instance's sidebar): 1.0
• Running flavour: social
• Running any extra/forked extensions: not as far as I know

Client device (please complete the following information):

• Device: Macbook Pro
• OS: MacOS 15.2
• Browser: Chrome
• Browser Version: 142.0.7444.135

Additional context
Not sure if these are significant but ...

• Neither of the accounts involved in testing have admin or mod privileges.
• The other account also successfully uploaded an emoji and was able to use it. But then after deleting it, they weren't able to upload the same emoji.
• I'm using local storage rather than an S3 bucket (not sure why this should matter but just in case!)
