Rob Fellows commented on NIFI-14237:
------------------------------------
Ah, yes. Glad you figured it out. I suspected as much and is why I asked about
running HTTP or HTTPS.
Good point about the paste button in the operation panel. It should be removed
as well since it can never work under the new approach taken with the
copy/paste action. As of 2.1, the copy/paste went from a completely internal
action to leveraging the system clipboard. The advantages of that are that now,
copy/paste works across browser tabs/windows. Also, as of 2.2, the flow
definition json stored in registries (the same format you get when you download
a process group) is supported as a paste-able format as well.
I've filed a Jira to address this:
