LookupError: Missing asset file for app-css

[mr-karan]

I'm trying to run this app inside Ubuntu 18.04 box. The steps I've followed (after setting up DB):

$ python manage.py createdb
$ cd hasjob/assets
$ yarn
$ yarn build

While trying to run the app:

The value of ASSET_BASE_PATH is set to '/static'. There's a /static folder on my local installation (which came after yarn build command).

ls -laht                 
total 28K
drwxrwxr-x  4 karan karan 4.0K Apr  1 20:19 .
drwxrwxr-x  2 karan karan 4.0K Apr  1 20:13 css

The error seems to be coming for a CSS file, but I do have baseframe-picked.css inside the static/css directory.

Is there any step I'm missing? Would love some help debugging this.

Thanks

Have you tried make from the base folder? Baseframe also has a make step, but that should be handled for you in its setup.py, unless something has broken lately.

Fixed it with this in my settings.py:

ASSET_MANIFEST_PATH = 'static/build/manifest.json'
ASSET_BASE_PATH = '/static/build'
STATIC_SUBDOMAIN = ''

Marking as resolved, thanks!

Place your local settings in instance/development.py or instance/production.py so they aren't in conflict with the git-backed instance/settings.py. The choice of development or production (default) comes from the FLASK_ENV environment variable.
