to find out more about setting up a project you can see this recording https://www.youtube.com/watch?v=AwL0QRxH9JQ&t=51s

in the blog post did you do step 3 "Create a new project on Adobe I/O Console to access Adobe Experience Platform Launch APIs"

My laptop is having a short in the wire between the keyboard and my brain.  sorryplease ignore

In Adobe Developer Console when you setup the project did you include Adobe I/O Runtime? 

I messed up this comment. Sorry... Please ignore 

We are not really experts on all the API's that project Firefly can be connected to.  We know a few of them well and others not so well.  On this particular question, I personally don't know the right answer.  I would go to their community and see if you can find the answer there?https://experiencel...

did you get past the issue?

With a page hosted at Adobe it will auto pass through your auth into the Action.This may seem like a silly question but do you have multiple orgs your a member of? If yes then in the right hand corner of your app page do you have the same org selected that the project was created in?  

Did you figure out the issue?

How are you trying to invoke the Action? Postman, localhost default app, adobe hosted default app? There are different tips and things to check for based on how you are interacting with it.  Is this the same question as https://experienceleaguecommunities.adobe.com/t5/project-firefly-questions/quot-...
