@MattWho refering to nifi-registry-bootstrap.log we use v0.3.0 But I'm pretty sure that I didn't watch this behaviour before using NiFi 1.10.0 (former version 1.9.2). Can you confirm this connection with the NiFi version? Thanks!

Hi all,
there are process groups in my NiFi (1.10.0) which contain disabled processors. These process groups are versioned and all changes are committed.
As soon as the NiFi instance is restarted these process groups are marked as changed and "show local changes" here:
I would like to know if this behaviour of NiFi is "normal". So far I have not noticed this fact. It is misleading when uncommitted changes are shown and it is not possible to avoid that disabled processors are included.
Does anyone know the phenomenon described above? Is there a solution for it?
Thanks for any advice.

@stevenmatison Thanks for this information. Haven't found a hint to this problem. 1.10 is not ready for “production”... In terms of parameter handling or what does this mean?

Hi all,
tried to use the new parameter thing on PutEmail processor in 1.10.0.
Checked spelling and value a thousand times.
Doing the same thing with variables works fine.
Any help is appreciated!

Solved Cluster-node users (who obviously execute these actions via rest-api or toolkit cli) had no permission to work with restricted components. Added permission, startet NiFi new and it works. Would by helpfull if somewhere a message would come up to tell that this is an authorization problem...

I have a process-group which has to be started via rest-api. Principial it works to start the process-group but processors inside which are marked as "restricted" won't get started, f.e. ExecuteScript, PutFile. These processors remain stopped. No error message. In nifi-app.log are only the started processors listed. No word of the others. In the UI of course I can start these processors. How to solve this via rest-api? Thanks for any help. Using NiFi 1.9.2 SUPPLEMENT It is not a REST-API thing. Tried with NiFi Toolkit (/bin/cli.sh nifi pg-start -pgid 708358fc-016c-1000-0000-00000bf....). All processors get started excepted the restricted ones. So where is the cause and how to fix this?

Got it! There was one } missing. Thought if the editor shows the expression coloured it would by syntactical correct. So it has to be: ${RESPONSE:jsonPath('$.[0].id'):equals(${KONTO_BV}):
and(${RESPONSE:jsonPath('$.[0].antauschvon'):le(${now():format("yyyyMMdd")}):
and(${RESPONSE:jsonPath('$.[0].antauschbis'):ge(${now():format("yyyyMMdd")}):
or(
${RESPONSE:jsonPath('$.[0].antauschbis'):isEmpty()})}
)}
)
}

I'am struggling with Expression Language concerning nested and-/or-conditions. In my UpdateAttribute the variable KONTO_IST_AN should be getting the result in boolean which is provided by this expression. Sample content of RESPONSE (always exactly one element at one time): [{"antauschbis":"20191231","antauschvon":"20190101","id":"(422)"}] => expected result: true
[{"antauschbis":null,"antauschvon":"20190101","id":"(422)"}] => expected result: true
[{"antauschbis":"20190531","antauschvon":"20190101","id":"(422)"}] => expected result: false
[{"antauschbis":null,"antauschvon":"20200101","id":"(422)"}] => expected result: false Expression: ${RESPONSE:jsonPath('$.[0].id'):equals(${KONTO_BV}):
and(${RESPONSE:jsonPath('$.[0].antauschvon'):le(${now():format("yyyyMMdd")}):
and(${RESPONSE:jsonPath('$.[0].antauschbis'):ge(${now():format("yyyyMMdd")}):
or(
${RESPONSE:jsonPath('$.[0].antauschbis'):isEmpty()})}
)
)
} But there seems to by a syntax error because the attribute KONTO_IST_AN contains after execution of UpdateAttribute the above expression not the expected result. Checked all square and round brackets and can't finde my error. Could someone please tell me how to resolve this?

Hi @Andrew Lim thank you for this detailed and step-by-step information, exactly what I was looking for. But I do have some questions which perhaps are a little weird caused by having no experience with github. 1. If I get this right the connection to github is "only" to store the content of each versioned flow outside the server where the registry is installed? So it is some kind of additional safty. Is this right? 2. Following your description one has to decide either using nifi-registry or github? Or did I get this wrong? 3. What if I try to connect to github and then want (only) to turn back to nifi-registry? Will this cause any predictable problems? 4. Is there any restriction in a clustered environment? I would be greatful if you will answer this questions, thanks a lot!
