Description

I uploaded a template to a clustered instance of NiFi which presented me with a success dialog. This, and subsequent actions, were performed through a node, nifi1. Upon trying to add this template to the canvas, I received a message that

Node nifi2:8443 is unable to fulfill this request due to: Unable to locate template with id '76c907b3-2664-30e4-987b-e9021ebcc844'.

Upon performing an inspection on several of the nodes in the cluster, I saw that all but nifi2 had the above listed UUID, but nifi2 had a different UUID. Upon trying to delete the template, I was presented with the same error. This behavior, inclusive of the error message was the same when performing the same actions on nifi2.

Re-uploading the template with a different name, everything worked as anticipated.

There was nothing of note in nifi-app or nifi-user logs beyond the information provided in the error dialog. Of possible note is that the node in question was possibly having some intermittent network issues but was listed as continuously connected on the node I was accessing.
