OAuthService.storeAccessTokenResponse(): ERROR TypeError: grantedScopes.split is not a function

[bspire]

I am getting the following error when the access token is stored:

OAuthService.storeAccessTokenResponse(): ERROR TypeError: grantedScopes.split is not a function

This happens because at this line grantedScopes is assumed to be a string which is in fact an array in my case:

Here is my configuration:

export const authConfig: AuthConfig = {
    clientId: 'xxx',
    dummyClientSecret: 'xxx',
    loginUrl: 'https://api.netatmo.com/oauth2/authorize',
    scope: 'read_station',
    requireHttps: true,
    oidc: false,
    redirectUri: 'http://localhost:4200',
    tokenEndpoint: 'https://api.netatmo.com/oauth2/token',
    showDebugInformation: true,
    requestAccessToken: true,
    responseType: 'code'
}

I use angular-oauth2-oidc version 8.0.4.

Best regards,
Stefan

As far as I've seen, the scope should always be a space-delimited string, not an array. If I read it right RFC 6749 says the same. So I'd hazard a guess that your Identity Server is not complying?

To prevent this issue, beginning with v 9.1, the lib checks now if it is a string.
