I had same problem when trying it in docker in local VM. Looks like for me helped downloading newer go version.
Edit Dockerfile and change second RUN command where go version is downloaded to

RUN mkdir -p /usr/local/ && \
    curl -OL https://go.dev/dl/go1.20.3.linux-amd64.tar.gz && \
    tar xf go1.20.3.linux-amd64.tar.gz -C /usr/local

It would be good if someone can rewrite the Dockerfile using a more modern Ubuntu version so it can use the system Go version instead of an external one.

I guess this is #57 which still needs to be merged.
