Fresh Docker development environment throws builtins.KeyError

See original GitHub issue

After many a try with fresh installation (removed all Docker containers, images, and volumes, rm -rf project_name) Django container invariably throws:

builtins.KeyError
KeyError: 'common'

while visiting /,/about,/users,/accounts, Django admin pages work as expected.

I’ve run into the same problem and this is what I’ve surmised of the issue:

There are only two entry points defined in the Webpack configuration file (main and vendor). In the base.html template there are references to three bundles (main, vendor and common). Since there is no common bundle, you get the KeyError you’re experiencing.

The fix is to remove {% render_bundle 'common' %} from the template file.

@jimbofreedman no, I haven’t. This is not limited to Docker environment. I have set up a fresh project with local development environment and Webpack. Same error, but this time more debug information:
