error trying to compile-graph

Hi,
I have latest vosk running on ubuntu 20.04, latest kaldi.
I downloaded the vosk-model-en-us-0.22-compile, and just added one simple new word to existing extra.txt. I run compile-graph.sh but getting what I think are errors:
mkgraph.sh: expected data/lang_test/G.fst to exist
expected data/en-mix-small.lm.gz to exist

Attaching full logs. Any help would be appreciated.

And questions, let's say it will compile successfully, what are my next steps? (will it produce a directory with files/folders such as am, conf, graph, ivector) that I can move to the model directory?
