Error exception "Expected keys to be an array of string" on Vercel deployment

[obsnomad]

Expected Behavior
No error when calling getAll().

Current Behavior
Working fine on dev environment, throws "Expected keys to be an array of string" exception on Vercel deployment.

Possible Solution
https://github.com/vercel/edge-config/blob/9689e9a0e21bba231e802074096a5a338f83c64f/src/index.ts#L257 should be conditioned like on line 265.

Was just arriving to call out the same issue. The assertion appears at odds with the functionality! 🥷🤺

https://github.com/vercel/edge-config/blob/main/src/index.ts#L34-L40
https://github.com/vercel/edge-config/blob/main/src/index.ts#L256-L262

Quick suggestion:

        if (localEdgeConfig) {
          if (keys !== undefined) {
            assertIsKeys(keys);
          }

          return Array.isArray(keys)
            ? Promise.resolve(clone(pick(localEdgeConfig.items, keys)) as T)
            : Promise.resolve(clone(localEdgeConfig.items) as T);
        }

Perhaps more accurately:

        if (localEdgeConfig) {
          if (keys === undefined) {
            Promise.resolve(clone(localEdgeConfig.items) as T);
          }

          assertIsKeys(keys);
          return Promise.resolve(clone(pick(localEdgeConfig.items, keys)) as T)
        }

Closing this as it shipped in #61
