bitcoin core – Failed to generate debug log in functional test

adminAugust 26, 2024

I’m working on a PR to migrate all the test-only rpc’s. -test rpc. I am facing an issue in one of my functional tests. feature_config_args.py Node does not generate debug logs. Here is the test_framework.log.

The failed tests are not related to any changes I made to the file and I can’t figure out why debug.log isn’t being generated.
