Unable to read environment variable #207

Open RohanVardhan opened 4 years ago

RohanVardhan commented 4 years ago

I want to pass url set in the environment variable as follows:

introspection: ${GRAPHQL_URL}

But I am getting this error - Error: The protocol "" is not supported, cannot load "${GRAPHQL_URL}". However, if I replace it with actual URL, it is working correctly. Could someone help me out with this error. Thanks.
