Whitenoise crash in Docker image building from missing Bootstrap .map file

[mikkonie]

Dump of error in comments. Nothing has changed in the include files themselves, so this must be a problem with the currently used version of Whitenoise. Not the first time we've encountered something similar.

Dump of crash in comments. See also #1666, #1992.
