Provider not being initialized properly on startup

[rajeshkp]

Provider not being initialized properly on startup, while trying to access the Keycloak server from a React JS client (refer https://github.com/dasniko/keycloak-reactjs-demo) shows the following initialization error. How do we get around this config+initialization problem

Getting the following error while try to login the page with the above jar:
