Remove the local ${PYTHON} python (and python3) variable definitions from
the *** Variables *** sections of all affected robot files. These local
definitions were overriding the pabot-injected venv Python path passed via
--variable PYTHON:/path/to/venv/python, causing tests to use the system
Python (which lacks required packages like structlog, sqlalchemy, etc.)
instead of the nox venv Python.
The correct ${PYTHON} value is already set by Setup Test Environment in
common.resource via sys.executable, and pabot passes it via --variable.
The local fallback definitions are redundant and harmful in parallel runs.
Audit found 56 robot files with the pattern (more than the 9 originally
identified in the issue). All occurrences have been removed.
