token_failed, Failed to get token

[itskgore]

I'm getting the following error after 3 attempts of a successful token refresh method calls in the 4th attempt I'm getting the following error:

PlatformException(token_failed, Failed to get token: invalid_grant: The refresh token is invalid or expired., null, null)

I'm using OKTA for OAuth.

This is my method:

final oktaRefresh = await appAuth.token(TokenRequest(
            '${Repository.env!['OKTACLIENTID']}',
            '${Repository.env!['OKTAREDIRECTURL']}',
            discoveryUrl:
                'https://${Repository.env!['OKTADOMAIN']}/oauth2/${Repository.env!['OKTAUTHORIZER']}/.well-known/openid-configuration',
            refreshToken: refreshToken,
            grantType: "refresh_token",
            scopes: ["openid", "profile", "offline_access"]));

I am encountering the same issue and am unable to determine whether it originates from the Okta console or the app itself

Are you seeing this on Android only or iOS and Android, noticed today the 1st token refresh on Android in a B2C flow is throwing this error and the 2nd attempt works but on iOS it works fine

@MaikuB I've tried this but no luck, Also, this is coming for iOS for 3rd time only the first 2 times it works fine.

Hello, I had this problem, (I use a Keycloak) my refresh tokens works 2-3 times but never more. So I migrated to this package oidc and I still had the problem. I solved it by adding offline_access to the scopes.

(I find OIDC easier to use, it automatically handles token refreshes and has a basic implementation for FlutterSecureStorage).

Hopefully this helps someone.
