Proposed fix: [micropip] 'Cannot install <req>: micropip only installs prebuilt wheels and does not support installing from a VCS URL (git+, hg+, svn+, bzr+)' / 'Requested <req>, but <pkg>==<v> is alr

Recommended action: Install from a wheel URL or index name instead of git+; pass reinstall=True (or micropip.uninstall first) to change versions; check the package name and index_urls. Option: Install from a wheel URL or index name instead of git+; pass

Proposed fix: [librdkafka SSL/SASL_SSL in slim containers] 'SSL handshake failed: ... certificate verify failed: broker certificate could not be verified, verify that ssl.ca.location is correctly conf

Recommended action: Install ca-certificates in the image (or set ssl.ca.location to the CA bundle / private CA PEM); on macOS use Homebrew openssl or ssl.ca.location=probe; never disable verification in production. Option: Provide a CA bundle [evidence: official_recommended_actio

Proposed fix: [pip] 'Cannot import build backend 'X'.' (backend-unavailable) — build-system.build-backend module missing from build env (wrong backend name, --no-build-isolation without the backend, b

Recommended action: Fix pyproject.toml ([build-system] requires includes the backend; build-backend path correct; backend-path for in-tree backends), or install the backend into the env when using --no-build-isolation. Evidence basis (self-declared by the contributing chat client

Recommended action: Upgrade the task to a version with Node20_1/Node24 handlers (or ask the extension owner). As a temporary escape hatch the message documents AGENT_RESTRICT_EOL_NODE_VERSIONS=false. Option: Upgrade the task major version [evidence: official_recommended_action] A

Proposed fix: [Claude Code skills] 'Shell command permission check failed for pattern "..."' — injected command hits a deny/ask rule or isn't pre-approved

Recommended action: Pre-approve the commands with `allowed-tools` in the skill frontmatter; deny and ask rules still override it. Option: Pre-approve the commands with `allowed-tools` in the skill frontmatter; deny and ask rules still override it. [evidence: official_recommended_

Proposed fix: [AWS Lambda Python] 'Runtime.MarshalError: Unable to marshal response: Object of type X is not JSON serializable' — handler returns datetime/Decimal/bytes/custom objects

Recommended action: Convert the result to JSON-safe types (str for datetime, int/float/str for Decimal) or return json.dumps(result, default=str) in an API Gateway body. Option: Serialize explicitly [evidence: official_recommended_action] Applies when: See record scope. Steps: 1.

Proposed fix: [pip] 'Cannot install build dependencies' (failed-build-dependency-install) — isolated build env can't fetch setuptools/wheel/other build-system.requires (offline --no-index, private ind

Recommended action: Add the build backend wheels to the wheelhouse/mirror (`pip download setuptools wheel <backend>`), or prebuild wheels on a connected machine; alternatively use --no-build-isolation after installing build deps into the target env yourself. Option: Provide build

Proposed fix: [librdkafka / confluent-kafka] 'No provider for SASL mechanism GSSAPI: recompile librdkafka with libsasl2 or openssl support' — sasl.mechanisms left at default GSSAPI when enabling SASL

Recommended action: Set sasl.mechanism (alias of sasl.mechanisms) explicitly to the provider's mechanism (e.g. PLAIN for Confluent Cloud/Event Hubs, SCRAM-SHA-512 for MSK SCRAM) with credentials; only rebuild librdkafka with libsasl2 if you really need Kerberos. Option: Set the m

Proposed fix: [micropip / Pyodide] ValueError "Can't find a pure Python 3 wheel for '<pkg>'" — package has only an sdist or compiled wheels not built for Pyodide

Recommended action: Check PyPI 'Download files' for *py3-none-any.whl; if pure Python, build the wheel yourself and micropip.install(<wheel URL>); if it has native code, use a package shipped with Pyodide or request Pyodide support; use keep_going=True to list all missing wheels

Proposed fix: [Claude Code on Bedrock behind gateway] 'Bedrock streaming response has content-type "text/event-stream"; expected "application/vnd.amazon.eventstream"' (formerly 'Truncated event messag

Recommended action: Configure the gateway to pass InvokeModelWithResponseStream body and Content-Type through unmodified; CLAUDE_CODE_DISABLE_BEDROCK_CONTENT_TYPE_GUARD=1 only hides the error (slower non-streaming path). Option: Configure the gateway to pass InvokeModelWithRespon

Proposed fix: [librdkafka] 'Disconnected: ... requesting ApiVersion: might be caused by incorrect security.protocol configuration (connecting to a SSL listener?)' / '...broker might require SASL authe

Recommended action: Set security.protocol to the listener's protocol (managed clouds: SASL_SSL + sasl.mechanisms=PLAIN/SCRAM/OAUTHBEARER + credentials) and verify the port matches that listener. Option: Match security.protocol to the listener [evidence: official_recommended_actio

Proposed fix: [gopls] Files with custom build tags (//go:build mytag), cgo files for non-host GOOS, or modules outside go.work get no analysis ('No packages found' class) — set build.buildFlags -tags

Recommended action: Add "build.buildFlags": ["-tags=mytag"] and/or GOOS/GOARCH in "build.env"; use a go.work listing the modules you edit together; verify with `go build ./...` outside the editor. Option: Configure build flags/env for gopls [evidence: official_recommended_action]

Proposed fix: [Kafka in Docker + librdkafka clients] bootstrap to localhost:9092 works, then 'Failed to resolve 'kafka:9092'' / 'Local: Host resolution failure' or connection refused — broker advertis

Recommended action: Configure separate listeners: an internal one advertised as kafka:29092 for containers and an external one advertised as localhost:9092 (mapped port) for the host; point each client at the listener for its network. Option: Dual listeners [evidence: documented_

Proposed fix: [setuptools/distutils builds] "error: command 'gcc' failed: No such file or directory" (or 'x86_64-linux-gnu-gcc', 'cc', 'clang') — no C compiler in slim/Alpine/distroless build images

Recommended action: First try to get a wheel (upgrade pip, use a Python/arch with wheels, glibc image instead of Alpine). Else install the toolchain: Debian `apt-get install build-essential python3-dev`, Alpine `apk add build-base python3-dev`, macOS `xcode-select --install`; use

Proposed fix: [AWS Lambda Python] 'Runtime.ImportModuleError: Unable to import module 'lambda_function': No module named 'lambda_function'' / 'Runtime.HandlerNotFound: Handler 'x' missing on module' —

Recommended action: Zip the file contents (not the parent folder) so lambda_function.py is at the root, or set Handler to pkg/module.func; ensure the function name matches; don't name the handler module after a built-in (e.g. sys). Option: Fix the zip
