Missing version for native driver

Error message

Missing version for native driver: {driver}

What it means

version_agent_artifacts() requires a version string for every driver listed in NATIVE_DRIVERS. If the supplied versions dict lacks an entry for a driver, it raises ValueError naming the missing driver, because the renamed artifact filename must embed the version. This fails fast before any files are renamed with an invalid name.

Solutions

1. Populate the versions dict with an entry for the named driver before calling version_agent_artifacts
2. Check upstream version-extraction output (e.g. Maven/package metadata) for the missing driver
3. Compare the versions dict keys against NATIVE_DRIVERS to find the mismatch/typo

Example fix

// before
version_agent_artifacts(release_dir, {"hive": "1.2.0"})  # zookeeper missing
// after
version_agent_artifacts(release_dir, {"hive": "1.2.0", "zookeeper": "3.9.1", ...})

missing = set(NATIVE_DRIVERS) - set(versions)
if missing:
    raise ValueError(f"versions missing drivers: {missing}")

try:
    version_agent_artifacts(release_dir, versions)
except ValueError as e:
    fail_build(f"version resolution incomplete: {e}")

When it happens

Trigger: Calling version_agent_artifacts(release_dir, versions) where versions does not contain a key for one of the NATIVE_DRIVERS (e.g. 'hive', 'zookeeper', 'sqlite-worker').

Common situations: A build step that extracts component versions failed silently and produced an incomplete versions dict; a new native driver added to NATIVE_DRIVERS but not wired into the version-resolution step; typo in the dict key.
