The ISOLATION_ID variable is not set. Defaulting to a blank string.

[UBgood]

I'm trying to run

sudo docker-compose -f sawtooth-build.yaml up

But I'm getting the following error:

WARNING: The ISOLATION_ID variable is not set. Defaulting to a blank string. ERROR: no such image: sawtooth-validator-local:: invalid reference format

Is this issue because I didn't set up a http proxy?

I am using ubuntu 22.04LTS and docker version 23.0.1.

create a file named http_proxy.conf and add ur http and https proxys there , and reload and restart the docker daemon , it should work after that
