Dropbox Community ModeratorI'll be happy to help with any issues you're having with the Dropbox API, but I'll need some more information. Please reply with:
- the name and version number of the platform and SDK/library you are using, if any
- the steps to reproduce the issue, including relevant code snippet(s), but don't include any access or refresh token(s)
- the full text of any error or unexpected output (the output you shared here doesn't seem to show the full error message from the Dropbox API/SDK)
hi sir,

var dpClinet = new Dropbox.Api.DropboxClient(TokenKey);
try
{
UploadArg uploadArg = new UploadArg(folder, WriteMode.Overwrite.Instance, true);
using (var mem = new MemoryStream(File.ReadAllBytes(fileToUpload)))
{
// var mem = new MemoryStream(File.ReadAllBytes(fileToUpload));
// var updated = await dpClinet.Files.UploadAsync(uploadArg, mem);
//var updated = await dpClinet.Files.UploadAsync(folder, WriteMode.Overwrite.Instance, body: mem);
FileMetadata fileMetadata = await dpClinet.Files.UploadAsync(folder, mode: WriteMode.Overwrite.Instance, autorename: false, body: mem);}
}

Hi senthilnathan205,
At the beginning, one error not directly related to the current issue, but will bring up soon, if let unfixed in advance. In your client initialization you are using access token only. This type of token is with limited validity (at most 4 hours). After that, user will need to relink your application again and again... To avoid such continuous token expiration, you have to initialize you client object with refresh token, access token expiration time, and application key (application secret might be need too depending on selected authentication type) in addition to the access token. If need, change your authentication flow.

Hm...🤔 What's the content of 'folder' passed as 'path' parameter? Take in mind that path has to point to the target file (full path) where the 'body' will be put to, not to the containing folder only! Dropbox can NOT know what's the desired file name, if not pointed explicitly. 😉
Hope this gives direction.
hi sir,
I replace token key each 4hr

senthilnathan205 I just tried this code, plugging in my own values and access token, with v6.25.0 of the library, and it ran successfully for me.
Is that the entirety of the error output?
Also, is there anything on your network connection, such as a proxy, firewall, VPN, anti-virus, etc., that may be interfering with your connections to content.dropboxapi.com? You may need to contact your network admin for help with that.Hi Greg-DB
thanks for reply. I use sample project to check the code it work correctly, but i use the in form behavior in Rapid flow here only not work.
