Adobe Launch - Adding resources to library in launch via the reactor api is not working

Question

I'm in the process of writing a script that will allow the user/dev to update launch using the reactor(launch) api without having to make use of the GUI. I'm at the point where I'm setting up the functionality to add resources to a library and I'm getting an error that says, "Rule /Data Element {resource} is invalid because it needs to be revised." I've attached a screenshot. I don't understand what this means. I'm assuming it might have something to do with needing to add a specific resource revision, but that's not listed in the Reactor API documentation. Does anyone know how to overcome the error?

This is documentation I've been following:
https://developer.adobe.com/experience-platform-apis/references/reactor/#tag/Libraries/operation/addLibraryRules
https://experienceleague.adobe.com/docs/experience-platform/tags/api/endpoints/libraries.html?lang=en#add-resources

Wow, you are going far down the road. I only use reactor API to export Launch configuration and not to maintain it, as I believe that will be LOTS of work to do.

To your question, I guess you also need to check how to manage the revision of a Launch component. As suggested by the error message and can be observed in the Launch UI, Launch components have revision and every time you make a change to a Launch component and add that into Library, you are adding a revision to the Library. Sorry that is not a solid answer but guess it is the direction you need to look at.

Though documentation may be slim on issues like this, I can often find the solution by doing the task manually in the Launch UI and watching the network calls made to "reactor.adobe.io" from the Launch client.
