The cause is that there are some containers with environment variables without value.

            "Env": [
                "http_proxy",
                "https_proxy",
                "no_proxy",
                "SERVICE_8052_NAME=awx2",
                "SERVICE_8052_TAGS=proxy-http,infra",
                "LDAPTLS_REQCERT=never",
                "PATH=/usr/pgsql-10/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",
                "LANG=en_US.UTF-8",
                "LANGUAGE=en_US:en",
                "LC_ALL=en_US.UTF-8",
                "HOME=/var/lib/awx"
            ],

In InspectContainerMetadata these values are split by = and they are expected to result in 2 parts. This appears not to be true in all cases.
