25082510* If the message contains `context_management: Extra inputs are not permitted`, [update Claude Code](https://code.claude.com/docs/en/setup.md#update-claude-code) to v2.1.304 or later. After you update, Claude Code answers this rejection by sending the request once more without the field. Before v2.1.304, Claude Code didn't retry this rejection.
25092511* If the message names `defer_loading` or `tool_reference`, [update Claude Code](https://code.claude.com/docs/en/setup.md#update-claude-code) to v2.1.305 or later. Claude Code then answers this rejection by [sending the request once more](https://code.claude.com/docs/en/llm-gateway-protocol.md#retry-without-tool-search) without tool search fields.
25102512* If your gateway drops the header, configure it to forward the `anthropic-beta` header. See [feature pass-through](https://code.claude.com/docs/en/llm-gateway-protocol.md#feature-pass-through) for what gateways must forward.
2511* As a fallback, set [`CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=1`](https://code.claude.com/docs/en/env-vars) before launching. [Disable pre-release capabilities](https://code.claude.com/docs/en/llm-gateway-protocol.md#disable-pre-release-capabilities) covers the exact scope.

2513Before v2.1.302, this error could also name the field `diagnostics` with no gateway involved. It appeared when a session that had already used the Anthropic API moved to Amazon Bedrock or Google Cloud's Agent Platform without a restart. For example, a session you left open moves to Bedrock when you run [`/setup-bedrock`](https://code.
