DOCKER: Web interface doesn't work

[fartwhif]

EDIT: I just realized this is the wrong repository to post this issue. The one(s) who forked your project and posted this docker solution, deepai-org, decided to go without issue reporting, but you can close this if you want.

I apologize if there's a better place to report docker image problems.

After putting the value in the textbox and hitting upload/submit button the result is always: console displays a thrown exception and the web interface has no visible reaction. Different types of input all have the same result: raw input text or JSON (like the piped input example), or raw input text formatted as base64

exception follows:
