Attempting to read a nonexistent KV entry results in null, where cloudflare workers throws an exception

[Rysertio]

The example bellow, when ran using miniflare main.js -k TEST_NAMESPACE1 returns null.

// main.js
addEventListener("fetch", (e) => {
  e.respondWith(
    TEST_NAMESPACE1.get("key").then((value) => new Response(value))
  );
});

But when uploaded to cloudflare workers with the KV binding, it throws an exception.
In order to get the null response in cloudflare workers, a key must be created with null value.

Hey! 👋 Would you be able to share the exception that you're seeing? I've just tried this out using wrangler dev, and I'm getting null for non-existent keys which is consistent with the docs: https://developers.cloudflare.com/workers/runtime-apis/kv#reading-key-value-pairs.

Sorry, but it turns out the exception was due too trying too perform slice operations on null.
