Missing publisher origin for provider: ${provider}

Error message

Missing publisher origin for provider: ${provider}

What it means

providerOrigin could not resolve a publisher origin for a manifest provider: the provider's entry in PROVIDER_ORIGINS maps to null (resolveSourceOrigin failed for all of its hosts). This is a static registry-build defect in the ACTIVE_PROVIDERS manifest data — a provider lacks a usable host/origin — not a runtime user-input problem.

Solutions

1. Fix the provider's manifest entry in ACTIVE_PROVIDERS so it includes a resolvable host
2. Make providerOrigin return a safe default or skip the provider instead of throwing when the origin is missing
3. Add a registry unit test asserting every ACTIVE_PROVIDERS entry resolves to a non-null origin
