This test has one pipeline, so it also passes if restoration matches only by position. Add a reordered two-pipeline case to verify name-based matching. Add an unnamed-element case to verify the positional fallback branch.

- Line 180: Update restoreOmittedServiceSecrets to handle nil service entries
before dereferencing svc or accessing service IDs, returning the established
invalid-input validation error for null elements; alternatively reject them
during decoding. Ensure services containing null never reach secret restoration
or cause a panic before validateDatabaseSpec.

Sorry you missed my comment on this ticket: we have existing code that does this for database user passwords and backup/restore repository credentials. Could you please move this operation to database.Spec.DefaultOptionalFieldsFrom and make it consistent with our existing logic?

Make MCP secret parsing update-aware.
PostInitHandlers.UpdateDatabase validates MCP configuration before spec.DefaultOptionalFieldsFrom(existing.Spec) restores stored secrets. On existing MCP services, optionalString rejects empty or null embedding_api_key and kb_embedding_api_key. requireStringForProvider already accepts empty anthropic_api_key and openai_api_key during updates, but rejects null values. Update ParseMCPServiceConfig so these four secrets treat empty and null as omitted only when isUpdate is true. Preserve strict validation for new services and non-secret fields. Add tests for each empty and null case.

Summary
This PR fixes an issue where
GET /v1/databases/{id}strips sensitive service fields, such as RAGapi_key, for secret hygiene. However,UpdateDatabasevalidated the incoming spec before fetching the stored database spec. As a result, submitting the sanitized document returned by the GET endpoint back toUpdateDatabasewould fail with a400, even when the update was unrelated to services.The fix ensures the stored spec is fetched and the required secret values are restored before validation, allowing sanitized database specs to be safely used for updates without exposing or requiring clients to resend secrets.
Changes
Add
restoreSensitiveConfigandrestoreSensitiveValueinconvert.goas the inverse of the existingscrubSensitiveConfig. These helpers restore sensitive configuration values that are missing or blank in the incoming spec using values from the stored spec. Nested objects, such as RAG pipelines, are matched by theirnamefield.Add
restoreOmittedServiceSecretsto restore omitted secrets for existing services, matched byservice_id. Newly added services are unaffected and must provide their own required secrets.Reorder
UpdateDatabaseinpost_init_handlers.goto fetch the existing database and runrestoreOmittedServiceSecretsbeforeapiToDatabaseSpecperforms validation. This ensures omitted secrets are restored before validation rather than after the validation check has already failed.This follows the existing "omitted means preserve the stored value" behavior provided by
User.DefaultOptionalFieldsFromfor database user passwords, extending the same semantics to service secrets.Testing
Verification:
Created a database with RAG, MCP, and PostgREST services using valid API keys; all services successfully reached
service_ready: true.Verified via
GETthat no service secrets were exposed in the response.Submitted the unchanged
GETresponse back as an update. This previously returned400, but now succeeds. After the update, all services remainedrunningwithservice_ready: true, confirming that the stored secrets were preserved correctly.Checklist
