cloudflare-typescript KV Key metadata types too narrow

Between version 3.2.0 and 3.3.0 the type for KV's Key['metadata'] (and MetadataGetResponse) was changed from unknown to Record<string, unknown>.

This type is too narrow, as the metadata can be set to any valid JSON string. Since the value of the metadata is updated as a raw JSON string, this arbitrary nature is very useable. Presumably this is parsed by JSON.parse which respects this behavior. This can either be reverted to unknown, or widened to be a JSONValue type that is essentially most primitives.

I've raised an internal ticket with the KV team on this and asked them to weigh in. Thanks!

Don't know why this closed. We are actively working on it with internal ticket KV-1525.

I have no idea why the automation was closing this down. @musa-cf any idea?
