- Bluesky同様、投稿への反応を変更できるようになりました（画像参照）
- 画像にAltをつける機能/画像一枚ずつを削除する機能をv1から復帰させました。
- 「クロップ調整」を「サムネ調整」に名前を変更しました。また、サムネ調整ダイアログのUIを改善しました。
- 一部環境においてすべての投稿がBadRequestになる問題を修正しました。
- クリエイターモードの実装に向けた準備のため、バックエンドを大幅にリファクタしました。まだ先になりそうですが、お楽しみに。
Altがつけれるようになったよ。 v1であった機能の復帰ですが、今回はClaudeを使っているので、v1よりはずっと安定している...はずです。

surely

return result.WasSuccessful? Ok(result):BadRequest("It didn't work");

is all you need. Reads well, is concise, and any debug point goes into Ok() and BadRequest()

It's not a problem with ProblemDetails (per say) but the way the default error handling is defined for not-200-status codes.

If you:
- ✅ AddProblemDetails()
- ✅ UseStatusCodePages()

and then return
- BadRequest() -> app../json + PD result
- BadRequest("blah") -> app../json but not a PD result

👋🏻 G'day Tim. Issue isn't the BadRequest class, it's the baked in error handling for not-2XX Success message 'status codes'.

Check these docs out (and note the version I was looking at).

I think this doesn't apply to .NET 9+ ?

Hi ASP.NET Core Devs. Is this .. correct?

The Out-Of-The-Box ASP.NET application does not have support for 4XX and 5XX response's *which contain a body*
e.g.
- ✅ return BadRequest(); // No Body
- ❌ return BadRequest("name missing");

UseStatusCodePages only works with *no body*.

Good bot
The key check is [cmd/relay/relay/host.go (line 177)] // port numbers not allowed otherwise if u.Port() != "" { return "", false, fmt.Errorf("port number not allowed for non-local names") } That parser is used directly by public and admin requestCrawl in [cmd/relay/handlers.go (line 26)]. So if you call requestCrawl with: {"hostname":"https://whatever.example:3000"} the relay returns 400 BadRequest before trying to connect. The internal reason is exactly port number not allowed for non-local names. If instead you call requestCrawl with just whatever.example, the relay checks https://whatever.example/xrpc/com.atproto.server.describeServer on the default HTTPS port, effectively 443, via [cmd/relay/handlers.go (line 52)](/Users/kuba/Projects/indigo/cmd/relay/handlers.go:52) and [cmd/relay/relay/host_checker.go (line 57)]. If your PDS only answers on :3000, that check fails as HostNotFound. There is a second blocker during ingest too. When a repo event arrives for a new account, the relay resolves the DID, reads PDSEndpoint(), and runs the same ParseHostname on it in [cmd/relay/relay/account.go (line 70)]. A PLC endpoint of https://whatever.example:3000 fails as new account PDS endpoint invalid, so commits are not accepted/broadcast for that account.

v4.4.1 of layrz_sdk
A Flutter SDK for Layrz, providing tools and utilities for integrating Layrz services into your Flutter applications. Changelog excerpt: - Fixed `BroadcastStatus.BAD_REQUEST`(Go and Python) value to `BAD_REQUEST`, matching the platform's actual API response (was incorrectly `BADREQUEST`). - Added validation to `BroadcastResult.status`(Python) that accepts the legacy `BADREQUEST`string and coerces it to `BAD_REQUEST`. - Initial version on Dart implementation

Success property name is unnecessarily verbose.

I never compare booleans to literals but I do have slight sympathy for the readability argument.

Do we know BadRequest is always the correct response on failure? "it didn't work" definitely isn't.

Comments are redundant. Document properly.

こんばんは！いつもRPやいいねありがとうございます！

スマホでwebサイトを開こうとした時に「BadRequest」と出た場合は、サーバー側か端末側でエラーが起きてしまってい
のだと思われます。
専門知識があるわけではないので確実ではありませんが、同じ様なことが起きた時に私は「webサイトのキャッシュを削除する」や「スマホ端末の再起動」で回復しました。もしくはブラウザを変えてみるなどですかね。(iPhoneでしたらSafariが標準ですからChromeで試すなど）
参考になれば幸いです！
