Thank you @dcharbonnier for reporting the issue. This is caused by release of Python Cryptography v35, release on 29th Sept. To correct this issue enter following commands:

source ~/.platformio/penv/bin/activate
pip install "cryptography<4"
cargo +esp build

The issue is being discussed at https://matrix.to/#/#esp-rs:matrix.org FYI @ivmarkov

there is no ~/.platformio/penv/bin/activate

ivmarkov commented 2 years ago

It is somehow here: /root/.platformio/packages/framework-espidf/ - as the error message points out. Not sure how this /root is mapped out when using docker images.

The above is basically a quick workaround until, I guess - PlatformIO and ESP-IDF release an official patch. The issue is not even related to this example, but a generic one.

Given that this problem is pinned in the meantime, we can probably close this issue as a duplicate.
