RCurl working in interactive mode but not through non-interactive

[YvesCR]

I have a script which call Rcurl that I want to automate.

RCurl::getURL(path_folder_sftp , userpwd = "my_pwd" , verbose=TRUE , ftp.use.epsv=TRUE , dirlistonly = T)

It works well in interactive mode.

when using cmd or powershell: C:/PROGRA~1/R/R-3.6.0/bin/Rscript.exe "C:/test/my_test.R" >> "C:/test/log/my_test.log" 2>&1

It fails and return following error:

• Trying my.server.address...
• Connected to sftp.myaddress port 22 (#0)
• SSH MD5 fingerprint: numbers here
• SSH authentication methods available: publickey,password
• Using SSH public key file '(nil)'
• Using SSH private key file ''
• SSH public key authentication failed: Unable to extract public key from private key file: Unable to open private key file
• Initialized password authentication
• Authentication complete
• Connection #0 to host sftp.myaddress left intact

Not sure if it a RCurl issue though.

closing issue, here. Issue was due to different environment :(
