It doesn't look like the project that you're building went through the upgrade steps to use nerves 1.5.

Could you confirm that these steps were done? https://hexdocs.pm/nerves/updating-projects.html#updating-from-v1-4-to-v1-5

I'm also going to update the text for option 2 to be more helpful.

Confirming that those steps were incomplete and incorrectly implemented.
My apologies and thanks for your helpful insight. I'm building again on the latest versions ❤️
