Hi @rbartlet, thank you very much for your reply!
Yep, I’ve created the extension and the environment variables are configured as well.
Now that you mentioned I’m not exactly sure, and sorry for this noobish question, what should I write into the Testing Base Uri. If the dev-rig is running on https://localhost.rig.twitch.tv:3000/ and the extension is located at %root-repository%/test/ and I have there one file called test.html (it has the extension helper and all that stuff in the HTML code) what should the test uri be? This one? https://localhost.rig.twitch.tv:3000/test/
I have to mention that the paths for every view is test.html as well.
Edit: Just to add more info. I’ve configured a local IIS server running at http://localhost:8081/ and put the assets there (http://localhost:8081/test/test.html), then I went into the dev portal, configured the URI to http://localhost:8081/test/ just to try something else and still is “not working”. What I do notice though is that i’m getting a 404 from https://api.twitch.tv/v5/extensions/XXX/auth/refresh/rigtesting, maybe this could be the problem? Not sure how to fix it though.
Note: XXX is my client id and rigtesting is the EXT_CHANNEL
