Bug in Put Conditional?

[bstopp]

I'm trying to use the onlyIf conditional for putting an object into a bucket using R2 Bindings. However, I'm seeing the reverse of operations than expected.

I would expect that if I:

    const update = await env.BUCKET.put(key, 'New Content', { onlyIf: { etagMatches: '*' } });

This will only return an object if there already exists content at the specified key.

Whereas:

    const update = await env.BUCKET.put(key, 'New Content', { onlyIf: { etagDoesNotMatch: '*' } });

Will only save if there is no content at the specified key.

Using Miniflare, my tests show these are reversed, here's a gist for both cases.
