Testing core-metadata with x86_64

[kayielt]

I got a problem when I processed the command to test core-metadata with platform X86_64. I ran this command and it raised the result below. How can I fix this or maybe I made a mistake? Please give me advice thank you. (Edgex Foundry v2.3.0)

sh run-tests.sh x86_64 false functional-test core-metadata no-deployment
