Description

When the fileName uri option does not contain any folder information, ie: "fileName=filename.txt" the producer runs in exception

The exception is thrown when the producer calls ls method of jsch ChannelSftp passing an empty string as directory parameter in org.apache.camel.component.file.remote.SftpOperations.existsFile line 704

sample URI:
sftp://user@hostname:22?disconnect=true&eagerDeleteTargetFile=false%3Bstepwise%3Dfalse&fileName=SYSTEM01&password=******&soTimeout=30000&tempFileName=%24%7Bfile%3Aname.noext%7D.tmp
