agodnic 93427d6dfc [API] Fix serialization issue in HTTP responses (#204) ... ### Summary Several endpoints related to VAAs and observations returned `null` when no results were found. This commit changes the behavior to return `[]` instead, which is more ergonomic for users. Endpoints affected: - `GET /api/v1/observations/:chain` - `GET /api/v1/observations/:chain/:emitter` - `GET /api/v1/observations/:chain/:emitter/:sequence` - `GET /api/v1/observations/:chain/:emitter/:sequence/:signer/:hash` - `GET /api/v1/vaas/{chain_id}` - `GET /api/v1/vaas/{chain_id}/{emitter}` - `GET /api/v1/vaas/{chain_id}/{emitter}/{seq}`		2023-03-22 14:18:11 -03:00
