PutFTP NullPointerException

Hi everyone,

I hope everything is fine with you.

I'm having an issue with my nifi flow, I'm using nifi 1.26.0 and a PutFTP processor.

In queue, my files have attributes and everything is ok, but when the file goes to PutFTP it seems like it loses his attributes.

My processor gives this error

PutFTP[id=0193100b-ea3b-104f-002c-f975c98b8819] Processing halted: yielding [1 sec]: java.lang.NullPointerException: Cannot invoke "String.startsWith(String)" because "fullPathWithSlash" is null

Does anyone face something like that?

Thanks in advance.

Can you please share absolute path details? I am guessing error in that string statement.

@dan_lucas

From the exception, this appears to be a configuration issue most likely.
You'll want to verify the NiFi Expression Language statement used in the putFTP processor's "Remote Path" property.

I assume you have something configured there like ${absolute.path}/${airlinename} in that property?

If you manually connect to the FTP server can you successfully navigate the path?
