Admin API flow creation with duplicate IDs

How to generate unique node ID when creating a flow via node-red API

Hi Charlotte, I had the same problem as you. I have found that IDs are generated with this JScript function (1 + Math.random () * 4294967295) .toString (16); You can find it on file @node-red/util/lib/util.js, function generateId() I hope it is useful for you Ciao

Also the link to the Node-red util file with the code that generates the ids. (LINK)
You may implement the same method to give the nodes a unique id before the POST ?

[EDIT]
Why would you want to POST a flow with duplicate node ids which in my mind means a duplicate flow ?!
Maybe you should be using PUT /flow/:id that updates a Flow ?
