What would be a good method to diagnose

```plaintext
precompile target: desktop_theme 

rake aborted!

NoMethodError: undefined method `resolve_baked_field' for nil:NilClass

```

?

Step 1️⃣ would be to be on latest, are you?

After that I would disable theme by theme to find which is the problem one.

Yes .. this was bulk standard

```plaintext
./launcher rebuild app

```

on a staging site which as I understand it gets the latest version.

How do you disable themes on an instance that is not running?

Does it give you more than that? Typically, there’s a backtrace there.

Based on the solution another post with a similar issue.

I did the following

1. Added `DONT_PRECOMPILE_CSS: 1` to /var/discourse/containers/app.yml
2. `/var/discourse/launcher rebuild app` which worked
3. Selected a default theme in {{host}}/admin/customize/themes … no default theme was selected.
4. Commented out `DONT_PRECOMPILE_CSS: 1` in /var/discourse/containers/app.yml
5. `/var/discourse/launcher rebuild app` again, which worked.
