Does Object Storage support Conditional Writes (headers for if-none-match, if-match, etc)?

---

P.S. I tried to go to Discord to ask. I saw I needed to verify my account to ask/do anything. I did not have a Railway account (because I'm meerly trying to understand if Railway supports my use-case). I created an account. I went through the Railway/Discord OAuth flow. I am saddened, because I was not able to verify seeing this error (on https://railway.com/auth/error?provider=discord&msg=Problem%20completing%20OAuth%20login):

Error authenticating with Discord

Problem completing OAuth login

...I am further saddened that I only see one option under the (required) "Service" dropdown for this "Create Public Thread" form:

"N/A (This is unrelated to a Railway service)"

...followed by an alert [gaslighting] me:

Confirm N/A Selection

You selected N/A, which means this thread is unrelated to a Railway service. Is that correct?

...as though I have any other options.

P.P.S.

Ok, I think I failed to recognize the "Service" field as a free-form text input. If so, my bad.
