Api exception: invalid-refresh-token

[Achudh Krishna]

ApiException: apiUrl=https://<backendUrl>.nhost.run/v1/auth/token, statusCode=401, responseBody={status: 401, message: Invalid or expired refresh token, error: invalid-refresh-token}

Facing this issue when the session is automatically refreshed. I have a function which checks auth state and refreshes the token in the background.

  ///
  Future<bool> isUserLoggedIn(BuildContext? context) async {
    log(
      "FILEPATH: lib/src/core/services/auth_service.dart\n",
      name: "isUserLoggedIn()",
    );
    log(
      "Entering function isUserLoggedIn()...\n",
      name: "isUserLoggedIn()",
    );
    log(
      "Reading refreshToken from SharedPreferences...\n",
      name: "isUserLoggedIn()",
    );

    final String? storedRefreshToken = await _prefs.then(
      (SharedPreferences value) => value.getString("refresh_token"),
    );

    if (storedRefreshToken == null) {
      log(
        "refreshToken not found from SharedPreferences...\n",
        name: "isUserLoggedIn()",
      );
      isAuthenticated = false;
      //   notifyListeners();
      return false;
    } else if (!isAuthenticated) {
      try {
        log(
          "refreshToken found from SharedPreferences attempting to signInWithRefreshToken...\n",
          name: "isUserLoggedIn()",
        );
        log(
          "Calling:  nhostClient.auth.signInWithRefreshToken($storedRefreshToken)\n",
          name: "isUserLoggedIn()",
        );

        final AuthResponse response =
            await nhostClient.auth.signInWithRefreshToken(storedRefreshToken);

        log(
          "AuthResponse success; userId: ${response.user?.id}\n",
          name: "isUserLoggedIn()",
        );

        await _prefs.then(
          (SharedPreferences value) => value.setString(
            "refresh_token",
            response.session!.refreshToken ?? "",
          ),
          // ignore: always_specify_types
          onError: (e, s) {
            log(e.toString(), error: e);
            log(s.toString(), error: s);
          },
        );

        log(
          "SharedPreferences.write; refreshToken: ${response.session!.refreshToken}\n",
          name: "isUserLoggedIn()",
        );

        accessToken = response.session!.accessToken!;
        isAuthenticated = true;
        userId = response.session!.user!.id;
        notifyListeners();
      } on ApiException catch (e, s) {
        if (context != null) {
          context
              .read<SharedService>()
              .showToast(message: e.body["message"].toString());
        }
        log("FILEPATH: lib/src/core/services/auth_service.dart 184:49");
        log(
          "ApiException ERROR on isUserLoggedIn: \n${e.body}\n - stack: $s",
          name: "isUserLoggedIn()",
          error: e.statusCode,
          stackTrace: s,
        );
      } catch (e, s) {
        if (context != null) {
          context.read<SharedService>().showToast(message: e.toString());
        }
        log("FILEPATH: lib/src/core/services/auth_service.dart 194:49");
        log(e.toString());

  }

We have fixed this issue in our latest Beta version, you may check it out https://pub.dev/packages/nhost_sdk/versions/4.0.0-dev.9

You need to remove backendUrl and add subdomain and region

Hi @mhadaily big fan of yours! Thank you so much for all your contribution to open-source community! Can we expect a video tutorial of nHost with Flutter in your channel any time soon?

PS: Thank you for resolving the issue!

@Achudh Thank you my friend.

Yes, I have planned a complete course on Full stack Nhost and Flutter and will start recording as soon as I release version 4.0.0 Stable.

I don't think I'm facing the issue anymore. Thank you so much @mhadaily
