Cannot find the package of nodes my flow requires

Hello,

Complete Beginner here,

I am working on a flow forwarded to me by someone, and one of the nodes are not configured in my local system. on NODE RED website, it says the package has been removed.

How can I get the sender of this flow to send me his package and how can I install that file to include the package in my flow ?

If someone has shared a flow that contains a node you don't have installed, they need to tell you what module to install to get it, or you may be able to do some searching on flows.nodered.org to find it.

In fact, if you paste your flow in here: https://flows.nodered.org/inspect - it will give you a list of possible modules that provide the nodes it uses. You may still need to get the sender to clarify which one they used.
