Problems with URL Map Generation on Build (v 3.3.3)

Development
1

Hello, I’m working on a custom fork of the Indico codebase and recently I’ve been trying to effectively rebase to 3.3.3 (starting from 3.2.9), and webpack is failing with messages I think are related to missing entries in url_map.json.

Here’s an example:

ERROR in ../../modules/rb/client/js/common/bookings/actions.js
Module build failed (from ../../../node_modules/babel-loader/lib/index.js):
SyntaxError: /app/indico/modules/rb/client/js/common/bookings/actions.js: indico-url imports must reference a valid flask endpoint

I can’t figure out why the URLs are missing from the URL map JSON file, but this seems to be the root cause of the issue.

That file is auto-generated. Restarting the build-assets.py script should be enough, but if for some reason it’s not regenerating the file simply delete it.

Deleting the file and recreating it via build-assets.py did the trick. Thanks!
