Countries example didn't seem to work 'as is'.

I got it working by making the following changes:
• Changed inject to inject msg.junk instead of msg.payload.
Seemed unwilling to overwrite payload if already set to a string value.
If I tick 'show debug' the response is all down there in the object under debugInfo.data.data.

Thanks for documenting this @tonybroadbent. I was also having trouble with the example, and changing the inject-node to as you proposed fixed the issue. I'm running Node-RED version: v3.0.2 and Node.js version: v14.21.3.
