Whew! I finally got MediaConvert and Lambda successfully working in n8n to complete my podcast setup.
It was work, but I am pleased with the results. After a few hiccups during debug, I decided to modularize my setup to make it easier to troubleshoot, maintain and run, if once step failed while another might succeed.
It's a 4-step process, which runs pretty smoothly right now and each step can be independently run by pulling in completed steps from the master Google Sheet, which is the brains of the operation.
Check it out and let me know if you have any questions.
Thanks to you all for your support. I could not had done it without Nate's training videos :-)
