Botium-speech-processing failed to solve: executor failed running

When executing the file: docker-compose.yml which is in the link:

github:
/ codeforequity-at / botium-speech-processing / tree /master / connectors / rasa / client

It has an error.

[2/7] RUN apk add --no-cache --virtual .build-deps curl sed python make g++:

Inside the Dockerfile change it to:
RUN apk add --no-cache --virtual .build-deps curl sed python3 make g++

The problem persists

What do you recommend to be able to execute. I am using Ubuntu 20.04
