Admin API trying /nodes/:module to disable/enable node

General
1

Hi,
I must be blind or missing some essentials....
In the flow example below I try to disable the node but I do just get 400 as respond.

Getting the node information using GET works. Also the PUT "seems to work" when {"enabled":true} but there is in fact no change to the node even though the response is 200

The PUT method with the same msg structure fails when set to {"enabled":false}

Any hints are highly appreciated. Maybe I have misunderstod how this API call is ment to work??

NR version 4.0.5

Did you reload your browser after your PUT request?

There must be another reason but this will ensure that the editor is in a clean state.

Andy's answer is indeed correct, you cannot disable a node that is in use.

possibly you get a 400 Bad Request error because you have al least one node in the flow.
from what i understand this api disables or enables the whole module .. not the specific instance of the node in a flow. and if it's in use you cannot (400).

Thank you very much guys!!
That was it, I acrually have one instance of the node running in the flow. Then I have to keep on using the api /flow as I already do and that works ok. I just thought that was a bit "overkill" since it is just one particular node I want to disable/enable to let it initiate itself again. I now realize that the api call is not acting on a running instance of a node but on the available collection in the palette. Is a pity, I think such an api call, acting on a running instance of a node, would be "nice to have"

Kind regards, Walter
