Proposed fix: [go-genai Live] 'live module requires APIVersion to be set. You can set APIVersion to v1beta1 for BackendVertexAI or v1apha for BackendGeminiAPI' (note typo 'v1apha')

Recommended action: Set ClientConfig{HTTPOptions: genai.HTTPOptions{APIVersion: "v1beta" or "v1alpha"}} for the Gemini API (spell v1alpha correctly) or "v1beta1" for Vertex, at client level, and do not set HTTPOptions on LiveConnectConfig. Option: Set a valid client-level API ver

Proposed fix: [Anthropic structured outputs] 'pattern' regexes with backreferences, lookahead/lookbehind, \b word boundaries or large {n,m} ranges cause 400 errors

Recommended action: Rewrite patterns into the supported subset (no lookaround/backrefs/\b, small {n,m}) or drop the pattern and validate client-side. Option: Simplify the pattern and validate after parsing [evidence: official_recommended_action] Applies when: See trigger Steps: 1

Proposed fix: [mcp-publisher] 'not authenticated, run 'mcp-publisher login <method>' first' after upgrade — token storage moved to ~/.config/mcp-publisher/

Recommended action: Run mcp-publisher login <github|github-oidc|dns|http> again (in CI, login in the same job before publish). Option: Re-login [evidence: official_recommended_action] Applies when: See trigger Steps: 1. mcp-publisher login github 2. mcp-publisher publish Expected

Proposed fix: [Amazon Bedrock] Context-window overflow has no single error code — model-specific messages ('Input is too long for requested model', 'input length and `max_tokens` exceed context limit'

Recommended action: Detect overflow by substring across all known variants (and the stopReason model_context_window_exceeded), then compact/truncate; keep the list in one place and extend it when adding model families. Consider CountTokens before sending. Option: Use a combined o

Proposed fix: [Amazon Bedrock Runtime] ModelTimeoutException (HTTP 408) and ModelErrorException / ModelStreamErrorException (HTTP 424) — non-standard statuses that generic retry classifiers mis-handle

Recommended action: Classify Bedrock errors by exception name, not HTTP status: retry ModelStreamErrorException per docs, and for ModelTimeoutException reduce work per request (smaller max tokens/input) or switch to streaming. Option: Retry by exception name [evidence: documented

Proposed fix: [Django migrations] 'Conflicting migrations detected; multiple leaf nodes in the migration graph' after merging branches — run makemigrations --merge

Recommended action: Run 'python manage.py makemigrations --merge' (review the generated merge migration), or renumber/rebase one migration onto the other if it hasn't been applied anywhere. Option: Create a merge migration [evidence: official_recommended_action] Applies when: Div

Proposed fix: [mcp-publisher] DNS/HTTP login fails 'timestamp outside valid window (±15 seconds)' (clock skew) or 'github.io domains cannot be used with DNS/HTTP authentication'

Recommended action: Sync the clock (NTP) before login; for github.io use mcp-publisher login github. Option: Fix clock / use GitHub auth [evidence: official_recommended_action] Applies when: See trigger Steps: 1. sudo chronyc makestep (or enable NTP) 2. mcp-publisher login github

Proposed fix: [Amazon Bedrock Converse + Llama/Mistral] ValidationException 'messages.N.content: Conversation blocks and tool result blocks cannot be provided in the same turn.'

Recommended action: Split tool results into their own user turn; Strands retries once with tool-result turns separated when it sees this exact message; LiteLLM suggests litellm.modify_params=True to insert a dummy assistant message. Option: Isolate toolResult blocks in their own

Proposed fix: [Anthropic Go/C# SDK cloud clients] 'no workspace ID found; set WorkspaceID ... ANTHROPIC_AWS_WORKSPACE_ID' and 'no base URL found' (Claude Platform on AWS / Google Cloud clients)

Recommended action: Set ANTHROPIC_AWS_WORKSPACE_ID and AWS_REGION (or ANTHROPIC_AWS_BASE_URL) for AWS; set ANTHROPIC_GOOGLE_CLOUD_PROJECT and ANTHROPIC_GOOGLE_CLOUD_WORKSPACE_ID for Google Cloud, or pass them in ClientConfig. Option: Set workspace and region env vars [evidence: o

Proposed fix: [Anthropic SDK tool runner compaction] 'Params.Compaction cannot be set on a tool runner' / 'messages were changed while the conversation was being compacted'

Recommended action: Leave Params.Compaction unset; call runner.CompactBeforeNextTurn(config) when a threshold is reached; modify messages only after the compaction response is read; remove compaction edits from context_management first. Option: Use CompactBeforeNextTurn [evidence

Proposed fix: [Anthropic API] 402 billing_error ('There's an issue with your billing or payment information') is distinct from 429 rate limits and must not be retried

Recommended action: Treat 402 billing_error as non-retryable; notify the account owner to check payment details in the Claude Console (or AWS Marketplace for Claude Platform on AWS). Option: Stop and surface a billing action [evidence: official_recommended_action] Applies when: S

Proposed fix: [Anthropic SDK refusal fallback] 'Sending the `fallbacks:` request param is not supported when using the `BetaRefusalFallbackMiddleware` middleware'

Recommended action: Choose one: remove the middleware and send `fallbacks` with the server-side-fallback-2026-07-01 beta header, or omit `fallbacks` and let the middleware handle fallback client-side. Do not share fallback state between handlers. Option: Use exactly one fallback

Proposed fix: [Django migrations] 'InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency <app>.0001_initial' — typically AUTH_USER_MODEL switched to a custom user

Recommended action: For dev DBs, recreate the database and migrate from scratch. For production, follow the manual process referenced by Django (ticket 25313): fix schema, move data, possibly reapply migrations. Set a custom user model at project start; the model

Proposed fix: [MCP tools/call] unknown tool and invalid arguments surface differently by spec revision and SDK — JSON-RPC -32602 ('Unknown tool: x', TS 'Tool x not found') vs isError result ('Input va

Recommended action: Clients should handle both: surface JSON-RPC -32602 messages AND isError results to the model for self-correction; servers should follow the current revision (unknown tool → -32602, bad args → isError). Evidence basis (self-declared by the contributing chat cl

Proposed fix: [GitHub webhooks] Events lost while the receiver was down or returned 4xx/5xx ('invalid HTTP response') — GitHub does not automatically redeliver failed deliveries

Recommended action: Run a scheduled job that lists recent deliveries, finds failures and calls the redeliver endpoint; return 2xx only after durable enqueue. Option: Automate redelivery [evidence: official_recommended_action] Applies when: See trigger Steps: 1. cron: GET /repos/{

Proposed fix: [Alembic] 'Can't locate revision identified by '<rev>'' — alembic_version table references a revision file that no longer exists (deleted/renamed migration, other branch, DB from another

Recommended action: Restore the missing revision file if possible; otherwise (typically dev) run 'alembic stamp --purge <rev>' to unconditionally erase the version table then stamp a known revision, and verify the schema actually matches. Option: Restore the file or stamp

Proposed fix: [MCP TS SDK server-legacy mcpAuthRouter] 429 'You have exceeded the rate limit for client registration requests' — DCR limited to 20/hour per IP; clients re-registering every connect get

Recommended action: Persist registered client information on the client; on the server, tune or disable the register rate limit (rateLimit option) and configure trust proxy so IPs are correct. Evidence basis (self-declared by the contributing chat client): untested.
