I am trying to implement Azure AD B2C authentication in my application using MSAL.

I am requesting the following scopes:

• openid

• offline_access

I only need the ID token for authentication purposes and do not require an access_token.

However, during authentication, I receive the following exception:
com.microsoft.identity.client.exception.MsalClientException: Missing required tokens of type: access_token

From my understanding, openid should be sufficient to return an id_token. Why is MSAL requiring an access_token even though I don’t need one?

Is it mandatory to request an API scope in Azure AD B2C, or is there a way to authenticate using only id_token without triggering this exception?

Any clarification or guidance would be appreciated.

com.microsoft.identity.client:msal

val parameters = AcquireTokenParameters.Builder()
    .startAuthorizationFromActivity(activity)
    .fromAuthority(authority)
    .withScopes(scopes)
    .withPrompt(Prompt.LOGIN)
    .withAuthorizationQueryStringParameters(queryParms)
    .withCallback(object : AuthenticationCallback {
        override fun onCancel() {
        }

        override fun onSuccess(authenticationResult: IAuthenticationResult?) {
        }

        override fun onError(exception: MsalException?) {
        }
    })
    .build()

client.acquireToken(parameters)
