Handling error: UnsupportedGrantTypeException, Unsupported grant type: password

I am trying to set up spring security with oauth2.0 in my application. and I am getting an exception:

UnsupportedGrantTypeException, Unsupported grant type: password

Is there anything that I am missing in configuration?

error logs:

org.springframework.security.oauth2.common.exceptions.UnsupportedGrantTypeException: Unsupported grant type: password
    at org.springframework.security.oauth2.provider.endpoint.TokenEndpoint.postAccessToken(TokenEndpoint.java:134) ~[spring-security-oauth2-2.2.1.RELEASE.jar:na]
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_201]

In the configuration for your authorization server, when you extend AuthorizationServerConfigurerAdapter, you can set up the authorized grant types for each of your clients.

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory()
        .withClient("client1")
            .authorizedGrantTypes("password")
            .secret("{noop}secret")
            .scopes("read")
            .accessTokenValiditySeconds(600_000_000);
}

There is a full example in the spring-security authorization server sample.

I think your Oauth server doesn't support password grant type. This one is used for getting "access tokens". I think that you should look for grant types handled by your OAuth server
