ValueError: There is no existing handler with id 0 when executed >1 times programmatically

[msramalho]

ArchivingOrchestrator.run() is not idempotent, so sequential programmatic calls raise exceptions.

Known case:

auto-archiver/src/auto_archiver/core/orchestrator.py

Line 239 in 6d43bc7

logger.remove(0) # remove the default logger

will throw ValueError: There is no existing handler with id 0

if the auto-archiver is executed > 1 times in the same programatic setup.
