Fix: HTTP Error 500.30 - ASP.NET Core app failed to start after deploying to IIS

500.30 means your app threw during startup inside w3wp.exe. The real exception is already in the Windows Application event log under IIS AspNetCore Module V2. Read that first, then rank the fix: missing shared framework, x86/x64 app pool mismatch, missing config, or app pool permissions.

2026-08-04 errors flutter dart

Fix: No Material widget found in Flutter

Wrap the subtree in Material(type: MaterialType.transparency) or put the screen in a Scaffold. MaterialApp alone does not provide a Material ancestor, which is why TextField and InkWell assert.

2026-08-03 errors claude-code ai-agents

Fix: "Write(src/**) is not matched by file permission checks" in Claude Code

Claude Code only consults Edit(path) and Read(path) rules. A Write(src/**) allow or deny rule is accepted and then silently ignored. Use Edit() instead.

2026-08-01 errors flutter dart

Fix: A RenderFlex overflowed by N pixels on the bottom when the keyboard opens in Flutter

The keyboard shrinks your Scaffold body's max height, so a Column that just fit now overflows. Wrap the body in a scrollable instead of turning resizeToAvoidBottomInset off.

2026-07-31 errors flutter ios

Fix: CocoaPods could not find compatible versions for pod during a Flutter iOS build

Read the second line of the error, not the first. It names the cause: a stale Podfile.lock snapshot, a deployment target that is too low, or two plugins pinning the same transitive pod.

2026-07-31 errors flutter android

Fix: Gradle task assembleDebug failed with exit code 1 in a Flutter Android build

That line is a wrapper, not the error. Re-run with flutter run --verbose or ./gradlew assembleDebug --stacktrace, read the real Gradle failure, then fix that.

Fix: A Long MCP Tool Call Gets Auto-Backgrounded After Two Minutes Mid-Task

Claude Code 2.1.212+ moves any main-conversation MCP tool call still running at two minutes into a background task. Set CLAUDE_CODE_MCP_AUTO_BACKGROUND_MS=0 to stop it, raise the threshold to move the line, or send progress notifications from the server.

2026-07-31 errors flutter dart

Fix: Unable to load asset in Flutter after adding an image to pubspec.yaml

The asset key is missing from the compiled bundle, not from your disk. Fix the pubspec indentation, add the trailing slash, match the key exactly, then full restart.

2026-07-30 errors blazor dotnet

Fix: JavaScript interop calls cannot be issued at this time (Blazor prerendering)

Prerendering runs your component on the server with no browser attached, so IJSRuntime throws. Move the call into OnAfterRenderAsync, gate it on RendererInfo.IsInteractive, or disable prerendering.

2026-07-30 errors mcp claude-code

Fix: .mcp.json servers never start because the workspace is marked untrusted

Project MCP servers stuck at Pending approval are not misconfigured. Run claude interactively in the folder, accept the workspace trust dialog, then approve the servers.
