Hi there,
the exact error is '
Description Resource Path Location Type
CryptographyDeprecationWarning: Parsed a negative serial number, which is disallowed by RFC 5280. hello_world line 531, external location: C:\.espressif\python_env\idf4.3_py3.8_env\lib\site-packages\cryptography\x509\base.py C/C++ Problem


any idea?

Have the same issue, on both 2021 09 and 2021 06 eclipse with IDF 4.3.1. Looking forward to a fix.

Ahh found the git issue,

https://github.com/espressif/esp-idf/issues/7631

That fixed the problem for me.
