…owngrade The 'Install Elementary' step was using pip install './elementary[vertica]' which re-resolved dbt-vertica's dependencies, causing dbt-core to be downgraded to ~1.7.3. The older dbt-core is incompatible with newer protobuf (MessageToJson() missing 'including_default_value_fields' arg), breaking the subsequent 'Install dependencies' step (dbt deps). Since dbt-vertica is already installed with --no-deps in the prior step, we install elementary without the [vertica] extra to preserve the correct dbt-core version.

Summary
Fixes the Vertica CI failure in the "Install dependencies" step.
The "Install Elementary" step was running
pip install "./elementary[vertica]", which re-resolvesdbt-vertica's full dependency tree. Sincedbt-verticapinsdbt-core~=1.8, pip downgrades dbt-core from the latest to 1.7.3. That old dbt-core is incompatible with newerprotobuf(MessageToJson()lost theincluding_default_value_fieldskwarg), causingdbt depsto crash immediately after.The fix: for Vertica, install elementary without the
[vertica]extra —dbt-verticais already installed (with--no-deps) in the prior "Install dbt-vertica" step, so the extra is unnecessary and harmful. This mirrors the same approach already used in theelementaryrepo'stest-warehouse.yml.Review & Testing Checklist for Human
