UPDATE Ah dang…forgot to include this:
Windows 10
VSCode
esp-idf (espressif32 latest)
esp-wrover board
what kinds of things would cause the build to fail after getting all the way to the end and during the last couple of steps failing with a:
TypeError: 'NoneType' object is not iterableI suspect that isn’t the entire error message… can you give the full compile output?
This is the output from the build. I also started a verbose build, i will post both below:

*** [.pio\build\esp-wrover16\esp32.project.ld] Error 1
So I take it (since we’re operating in the dark here)… that this is with the ESPIDF framework, using a ESP-WROVER board (making this espressif32), on Windows?
I also find the earlier error peculiar, as that path (ending) doesn’t look right.

What board type have you specified… better still… what’s your complete platformio.ini (if you can share it)? Maybe there’s a typo there.

I figured it out with some help from the community. It appears I was using an old board.json format. I basically took the wrover kit board.json file and have been using it for a few versions of esp-idf and I had a legacy line left that was causing me some issues:
