Using TW_PATHPREFIX causes errors

[gnsiva]

Hi, thanks for putting this together, it has been very helpful.

I wanted to configure the path that tiddlywiki would be available at. It does appear at that path, but tiddlywiki itself is broken. The following minimal example demonstrates the issue.

docker run -p 8080:8080 -e TW_PATHPREFIX=/wiki nicolaw/tiddlywiki 

The UI shows the following errors

I did see this in the documentation: https://tiddlywiki.com/static/Using%2520a%2520custom%2520path%2520prefix%2520with%2520the%2520client-server%2520edition.html

Perhaps a comment to mention that additional changes are needed or perhaps something in init-and-run that automatically sets up path prefix would be great.
