Access token not beeing refreshed automatically

my application support old dropbox and the new one.

when creating the client i am creating it like this


client = new DropboxTeamClient(request.AccessToken, request.RefreshToken,request.Expires,ClientId,ClientSecret);

and then using it 

in this way 

first Way

var members = await client.Team.MembersListAsync().ConfigureAwait(false);

 

and this way 

Second Way

var account = await client.AsMember(request.AsMember).Users.GetCurrentAccountAsync();
var clientNew= client.AsMember(request.AsMember).WithPathRoot(new PathRoot.Root(account.RootInfo.RootNamespaceId));

var folders = await spaceclient.Files.ListFolderAsync(folderId);

 

 

my issue is after 4 hours when the token is expired 

When i calling the  first way i am getting an error 

Response status code does not indicate success: 400 (Bad Request).

it is look like it is failing on refreshing token .

 

the problem is that this request is not exist in the new client 

Team.MembersListAsync(). not exist in the new client

 

 

please advice 🙂

 

Any Update Please 

maybe this method client.Team.MembersListAsync() not handling as it should with the refresh token

    The first way looks correct, and that code is working for me when I supply valid credentials. Make sure you're supplying the correct and valid values. For example, make sure:

    • the refresh token is exactly as originally provided by Dropbox
    • the refresh token hasn't been revoked by the app or user
    • the client ID and secret, a.k.a., app key and secret, are exactly as originally provided by Dropbox
    • the client ID and secret, a.k.a., app key and secret, are for the same app as the refresh token

     

    For the second way, it is expected that "clientNew" would not have the MembersListAsync method, since the MembersListAsync method is only available on DropboxTeamClient instances, not DropboxClient instances. The AsMember method returns a DropboxClient instance to operate on a specific member, not the whole team. The WithPathRoot method sets the root for the files calls made by the client. Neither of these control the refresh process.

      ok, but if i am calling the first way 

      i am getting the error.

       

      I am trying to understand.

      after 4 hours i am creating the dropbox team client with all the correct data(access,refresh,secret etc..).

      but getting an error 

      can you try and reproduce it .

      create a new token with 4 hours.

      then wait 4 hours and then call the new dropbox team client with the token then you get before and call the client.Team.MembersListAsync()

      i even try to call the refresh token method manually  but this didn't work also 

       

       

      need your help 🙂

        Yes, I tried the code you shared, plugging in valid refresh token, etc. values, and it worked for me.

         

        Please review the list in my previous message for reasons why that would fail for you. Check and update your values as necessary to make sure you're providing correct and valid refresh token, etc. credentials.
