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.
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.
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.
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.
Fix: Your startup project doesn't reference Microsoft.EntityFrameworkCore.Design
Add Microsoft.EntityFrameworkCore.Design to the startup project that dotnet ef builds, not the project holding your DbContext, and pass -s in layered solutions.
Fix: Couldn't find a valid ICU package installed on the system in a .NET container
Your base image has no ICU. Either install icu-libs and icu-data-full, switch to an -extra image variant, or set InvariantGlobalization=true and accept ordinal-only string behavior.
Fix: Reflection-based serialization has been disabled for this application
This InvalidOperationException means PublishTrimmed or PublishAot flipped JsonSerializerIsReflectionEnabledByDefault to false. Fix it with a source-generated JsonSerializerContext.
Fix: "The model for context 'X' has pending changes" in EF Core 11
EF Core throws PendingModelChangesWarning when your model no longer matches the last migration snapshot. Add the migration, or fix the false positive behind it.
Fix: a Windows path in your agent config silently turns into a tab, a newline, or a Chinese character
Folder names starting with t, b, n, r or u make a Windows path parse cleanly as JSON and still resolve wrong. Use forward slashes or double every backslash.
