Getting 'SSH_FX_NO_SUCH_PATH' SFTP error, even though file exists #9114

Closed cassis163 closed 6 months ago

cassis163 commented 6 months ago

In what version(s) of Spring Integration are you seeing this issue?

6.2.4

Describe the bug During the development of a custom backup advice, I encountered the 'SSH_FX_NO_SUCH_PATH' SFTP error. The strange thing is that when I connect to the SFTP-server locally, it works fine. But it malfunctions when my Spring Boot project runs inside of a Linux Docker container. Yes, it is a classic 'it works on my machine' type of problem, but after quite a bit of debugging, I still have not found the issue.

The path used for checking if the file exists and eventually for its retrieval is to_wms/orders/15408213_Canonical.json. Prepending this path with '/' is something that I have also tried.

Honestly, I'm not sure if this is actually a bug. It might very well be misconfiguration on my part.

Here are some things that I have tried, but to no avail:

This is my backup method:

private void backupFile(SftpRemoteFileInfoDto remoteFileInfo, boolean isSuccess) {
        var filePath = getFilePath(remoteFileInfo);
        if (remoteFileTemplate.exists(filePath)) {
            remoteFileTemplate.get(filePath,
                    inputStream -> createAndSendBackupFile(inputStream, remoteFileInfo, isSuccess));
        } else {
            throw new FileBackupException("File {} does not exist");
        }
    }

Here is the stack trace:

To Reproduce

Use the SftpRemoteFileTemplate inside of an advice in a Linux Docker container and try to call either the exists or get method.

Expected behavior

The file should be retrieved succesfully.

Maybe there is supposed to be some permission enabled for such a command?

@cassis163 ,

Please, take a look here: https://github.com/spring-projects/spring-integration/issues/9123. Sounds like similar problem to yours when you try to remoteFileTemplate.get().

Looks like this one has to use a canonicaPath() as well.

Will fix it shortly.
