Failing to start `TzUpdatePeriodically` #9

Closed sodapopcan closed 2 weeks ago

sodapopcan commented 2 weeks ago

Hi there!

Today I randomly started getting an error without any code changes:

** (Mix) Could not start application my_app: MyApp.Application.start(:normal, []) returned an error: shutdown: failed to start child: Tz.UpdatePeriodically
    ** (EXIT) an exception was raised:
        ** (ArithmeticError) bad argument in arithmetic expression
            :erlang.+(nil, 1)

I've been actively working on this application the past couple of weeks without running into this (I've never run into it!) and just started happening today.

I have tried rm -rf _build deps ~/.hex to no avail.

I'm a bit out of date on my stack:

Erlang 26.2 Elixir 1.16.2

I'll perhaps try upgrading but wanted to report regardless. Let me know if there is any other information I can provide.

Thank you!

I'm so sorry, I just realized I reported this in the wrong repo. I'll close and open in the right one.
