@randerzander I haven't been able to reproduce this yet. Running a simple
GetFile -> RPG on minifi-cpp to a regular NiFi with InputPort -> LogAttribute,
I am seeing the two attributes come through correctly.
I'm trying to look at the rest of the s2s code to see how a Peer instance
could be created and not get the correct host or port. Would you be able to add
the following code to the end of the Peer constructor?
https://github.com/apache/nifi/blob/master/nifi-commons/nifi-site-to-site-client/src/main/java/org/apache/nifi/remote/Peer.java#L51
```
if (this.host == null || this.port == -1) {
throw new IllegalStateException("Unable to get host or port
from peerUrl" + peerUrl);
}
```
My theory is that it somehow the parsing of the URI is considered
successful, but it didn't actually find a host or port, since the Javadocs of
uri.getPort() say it can return -1. Let me know if you can get that stacktrace
from that added code to see what the peerUrl is when this happens. Thanks.
