Posted on by Osrid

Hello all, I would like to start off by saying that I am very new to Power Automate, this is my first attempt so I could be missing quite a few details.

I am trying to download files from an SFTP via power automate. I have the flow created, I can connect to the FTP and view the contents that I need to download but when it actually tries to download, It fails on the first file with error:

Microsoft.Flow.RPA.Desktop.Modules.SDK.ActionException: Can't download file: /XXXXXX/XXXXXXX/xxxxxx/xxxxxx.pdf. Error while deducing the file paths to use for the local copies.
at Microsoft.Flow.RPA.Desktop.Modules.FTP.Actions.Utilities.FtpUtilities.DownloadSingleFile(IFtpConnection connection, FolderObject downloadInto, String ftpFileDirectory, String fileName, FtpTransferType transferType, IfFtpFileExists ifFileExists, Boolean locateDir, String ftpRootDirectory)
at Microsoft.Flow.RPA.Desktop.Modules.FTP.Actions.Utilities.FtpUtilities.DownloadFiles(IFtpConnection connection, List`1 remoteFilePaths, FolderObject downloadInto, FtpTransferType transferType, IfFtpFileExists ifFileExists, Boolean locateDir, String ftpRootDirectory)
at Microsoft.Flow.RPA.Desktop.Modules.FTP.Actions.DownloadFtpFileAction.Execute(ActionContext context)
at Microsoft.Flow.RPA.Desktop.Robin.Engine.Execution.ActionRunner.Run(IActionStatement statement, Dictionary`2 inputArguments, Dictionary`2 outputArguments)

It creates the File in my downloads folder but there is no content, basically a corrupted file. I also noticed that sometimes it creates a folder named "Remote Desktop" with a subfolder named "TemporaryRDStorageFiles-{4B369669-1B6C-4B6F-98ED-EFA7606CA474}) and the files within this subfolder but power automate desktop still errors out.

Am i missing something here? Any help is appreciated.

I guess the Files variable you have used is a datatable and so you might want to use a For each loop to iterate through each of the files and then download them within the loop.

Having said that, if you have a pattern you can also give the extension and also with a wild card character.

Have a look at this video if not already seen.

Hi, thank you for taking a look.

I tried the for loop but got the same result. I watched the video and i am following the same steps but i still get the error. starting to think it might be a bug.

Hi @Osrid

I still think it could not be a bug.

Could you share the screenshot of the inside of the FOR loop.

Also can you print in a Display box and see what is the string being passed to the Download Files inside the For loop.

I have a PAD flow that has ran flawlessly for years at this point. Suddenly started getting the "Error while deducing the file paths to use for the local copies" error. Found only this thread mentioning it, everything else was about file paths that are too long. This is copying down from SFTP to a local folder on the C:\ drive, so the length wasn't an issue.

Anyway, rebooting the VM fixed it.
