A network automation project uses a GitLab CE pipeline with stages: lint, build, test, and deploy. The pipeline consistently passes the lint and build stages but fails at the test stage. The test job log shows: 'ERROR test_ospf_config.py::test_area_id - assert 0.0.0.1 == 0.0.0.0' followed by '1 failed, 12 passed'. The deploy stage never runs. A developer recently merged a change to the Jinja2 template that renders OSPF area configuration. What is the MOST likely root cause and correct next action?
