S3 Transfer Automation > The specified bucket does not exist

Hello,
I'm trying to use WinSCPnet to upload files to S3 using script task in SSIS.
This is my code (using Winscp version 5.14.1.beta) :
// Set up session options
SessionOptions sessionOptions = new SessionOptions
{
    Protocol = Protocol.S3,
    HostName = "<bucketName>.s3-eu-west-1.amazonaws.com",
    UserName = "*****************",
    Password = "***************************",
};
using (Session session = new Session())
{
    session.Open(sessionOptions);
    //logic here
}
The session is established but when I try tu put files I get this error :
The specified bucket does not exist
Here's my code :
string  LocalDirectoryPath = "C:\path\to\file";
string  RemoteDirectoryPath = "/<BucketName>/";
bool    DeleteSourceFiles = false;
TransferOptions transferOptions = new TransferOptions();
session.PutFiles(LocalDirectoryPath, RemoteDirectoryPath, DeleteSourceFiles, transferOptions);
When I change RemoteDirectoryPath to "/" I get another error :
WinSCP.SessionRemoteException: Copying files to remote side failed. Specify target bucket
In the WinSCP UI I have the same behaviour. If I use the following configuration it works :
HostName = "s3-eu-west-1.amazonaws.com"
Remote directory = "/<bucketName>"
But if I use :
HostName = "<bucketName>.s3-eu-west-1.amazonaws.com"
Remote directory = "/"
And try to drag some file I get this error :
Copying files to remote side failed. Specify target bucket

Could you please take a look at this ? Thank's

This is the correct solution. So use it in .NET assembly too.

Thank you for your reply.
I could not find the equivalent "Initial Remote Directory" in the .NET assembly.
If I try to connect using only :
HostName = "s3-eu-west-1.amazonaws.com"
I get this error :
WinSCP.SessionRemoteException: Access denied. Access Denied Extra Details: RequestId: 280C45C8BB312493, HostId: plUn**************rMlQA/pN************CEc/LR8******= Connection failed
With UI this is set in Advanced Site Settings dialog (https://winscp.net/eng/docs/ui_login_directories)
How could one do the same with the assembly code?
Thanks

Re: S3 Transfer Automation > The specified bucket does not exist

You already specify your bucket name in RemoteDirectoryPath that you pass to Session.PutFiles. That should be enough.
If that does not work, please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Re: S3 Transfer Automation > The specified bucket does not exist

No, it is not enough because the connection isn't even established.
The error occurs when I call session.Open(sessionOptions);, so before the Session.PutFiles is executed.
The same happens in the UI ; if I do not specify initial remote directory I get the same error.

I tried to use <bucketName>.s3-eu-west-1.amazonaws.com to bypass that behaviour but it resulted in another weird behaviour which is explained in the first post.

Here's the session log generated by WinSCP 5.14.1 beta :

Sorry, but I got lost. You wrote before:

Remote directory = "/<bucketName>"
So does it work or not? Or does it work partially only? Can you elaborate?

Anyway, try this:
sessionOptions.AddRawSettings("RemoteDirectory", "/bucket");

Re: S3 Transfer Automation > The specified bucket does not exist

Sorry if I haven't give good explanation of the problem.

IN WinSCP UI
Working configuration : Everything works fine (connection and files transfer)
HostName = "s3-eu-west-1.amazonaws.com"
Initial Remote directory = "/<bucketName>"

Not working configuration :
The connection works but error occurs when I try to put files
HostName = "<bucketName>.s3-eu-west-1.amazonaws.com"
Initial Remote directory = "/"

IN .NET ASSEMBLY
The connection is established correctly but when the PutFiles is executed it generates an exception.
I tried sessionOptions.AddRawSettings("RemoteDirectory", "/bucket"); but with no success too.
SessionOptions sessionOptions = new SessionOptions
{
    Protocol = Protocol.S3,
    HostName = "s3-eu-west-1.amazonaws.com",
    UserName = "*****************",
    Password = "***************************",
};
sessionOptions.AddRawSettings("RemoteDirectory", "/<bucketName>");
using (Session session = new Session())
{
    session.Open(sessionOptions);
    session.PutFiles(LocalDirectoryPath, "/", DeleteSourceFiles, transferOptions);
}

Hope this is clear for you.
Thank you for your help.

Re: S3 Transfer Automation > The specified bucket does not exist

I finally got it to work by changing this ligne :
session.PutFiles(LocalDirectoryPath, "/", DeleteSourceFiles, transferOptions);

with this one :
session.PutFiles(LocalDirectoryPath, "*", DeleteSourceFiles, transferOptions);

The * did the trick.
So it's OK for sessionOptions.AddRawSettings("RemoteDirectory", "/bucketName");

Thank you :)

Are you sure it's the * that "did the trick"? It should work even without the *:
session.PutFiles(LocalDirectoryPath, "/bucketName/", DeleteSourceFiles, transferOptions);

Sorry I meant :
session.PutFiles(LocalDirectoryPath, "*", DeleteSourceFiles, transferOptions);

Anyway this also works fine (just tested it):
session.PutFiles(LocalDirectoryPath, "/bucketName/", DeleteSourceFiles, transferOptions);

The only one that doesn't work is when using "/" as remote directory in the PutFiles method.

You cannot upload to root folder on S3.
