616616Amazon Bedrock streams `InvokeModelWithResponseStream` responses in a binary event-stream format with the header `Content-Type: application/vnd.amazon.eventstream`. A gateway or proxy between Claude Code and Amazon Bedrock must forward the response body and its headers, including `Content-Type`, as Amazon Bedrock sent them.

618If the gateway rewrites `Content-Type` to another value, Claude Code rejects the response with an error that begins `Bedrock streaming response has content-type`, naming the value it received. The common rewrite is `text/event-stream`, from an integration that re-emits the stream as server-sent events.

The common rewrite is `text/event-stream`, from an integration that re-emits the stream as server-sent events. For the `CLAUDE_CODE_DISABLE_BEDROCK_CONTENT_TYPE_GUARD` variable that the error message names, see [Bedrock streaming response has an unexpected content-type](/docs/en/errors#bedrock-streaming-response-has-an-unexpected-content-type).

620620If the gateway drops or blanks the header instead, Claude Code assumes the body is Amazon Bedrock's event stream and decodes it, so a body the gateway passed through unmodified keeps streaming.
