How to make encodeURI query parameters?

I'm trying to pass an array with parameters using encodeURI, but [object, object] is missing

await request.get(
  `/api/v1/endpoint?fields=${encodeURI([
     { field: 'reserve_id', value: reserve_id },
     { field: 'in_reserve', value: in_reserve },
  ])}`,
)

request: http://server.com/api/v1/endpoint?fields=%5Bobject%20Object%5D,%5Bobject%20Object%5D
