When using Claude Code with LiteLLM and non-Anthropic providers (Bedrock, Azure AI, Vertex AI), you may encounter "invalid beta header" errors. This guide explains how to fix these errors locally or contribute a fix to LiteLLM.

When using Claude Code with LiteLLM and non-Anthropic providers (Bedrock, Azure AI, Vertex AI), you need to ensure that only supported beta headers are sent to each provider. This guide explains how to add support for new beta headers or fix invalid beta header errors.

## How LiteLLM Handles Beta Headers
|
||||
|
||||
LiteLLM automatically filters out unsupported beta headers using a configuration file:
|
||||
LiteLLM uses a strict validation approach with a configuration file:
|
||||
|
||||
```
|
||||
litellm/litellm/anthropic_beta_headers_config.json
|
||||
```
|
||||
|
||||
This JSON file lists which beta headers are **unsupported** for each provider. Headers not in the unsupported list are passed through to the provider.
|
||||
This JSON file contains a **mapping** of beta headers for each provider:
|
||||
- **Keys**: Input beta header names (from Anthropic)
|
||||
- **Values**: Provider-specific header names (or `null` if unsupported)
|
||||
- **Validation**: Only headers present in the mapping with non-null values are forwarded
|
||||
|
||||
## Quick Fix: Update Config Locally
|
||||
This enforces stricter validation than just filtering unsupported headers - headers must be explicitly defined to be allowed.
|
||||
|
||||
If you encounter an invalid beta header error, you can fix it immediately by updating the config file locally.
|
||||
## Adding Support for a New Beta Header
|
||||
|
||||
When Anthropic releases a new beta feature, you need to add it to the configuration file for each provider.
|
||||
|
||||
### Step 1: Locate the Config File

|
||||
|

**Key Points:**
|
||||
- **Supported headers**: Set the value to the provider-specific header name (often the same as the key)
|
||||
- **Unsupported headers**: Set the value to `null`
|
||||
- **Header transformations**: Some providers use different header names (e.g., Bedrock maps `advanced-tool-use-2025-11-20` to `tool-search-tool-2025-10-19`)
|
||||
- **Alphabetical order**: Keep headers sorted alphabetically for maintainability
|
||||

## Fixing Invalid Beta Header Errors
|
||||
|
||||
If you encounter an "invalid beta flag" error, it means a beta header is being sent that the provider doesn't support.
|
||||
|
||||
### Step 1: Identify the Problematic Header
|
||||
|
||||
Check your logs to see which header is causing the issue:
|
||||
|
||||
```bash
|
||||
Error: The model returned the following errors: invalid beta flag: new-feature-2026-03-01
|
||||
```
|
||||
|
||||
### Step 2: Update the Config
|
||||
|
||||
Set the header value to `null` for that provider:
|
||||
|
||||
```json title="anthropic_beta_headers_config.json"
|
||||
{
|
||||
"bedrock_converse": {
|
||||
"new-feature-2026-03-01": null
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3: Restart and Test
|
||||
|
||||
Restart your application and verify the header is now filtered out.

|
||||
|
||||
### What to Include in Your PR
|
||||
|
||||
1. **Update the config file**: Add the new beta header to `litellm/anthropic_beta_headers_config.json`
|
||||
2. **Test your changes**: Verify the header is correctly filtered/mapped for each provider
|
||||
3. **Documentation**: Include provider documentation links showing which headers are supported

||||

||||

## Add support for new-feature-2026-03-01 beta header
|
||||
|
||||
### Changes
|
||||
- Added `new-feature-2026-03-01` to anthropic_beta_headers_config.json
|
||||
- Set to `null` for bedrock_converse (unsupported)
|
||||
- Set to header name for anthropic, azure_ai (supported)
|
||||
|
||||
### Testing
|
||||
Tested with:
|
||||
- ✅ Anthropic: Header passed through correctly
|
||||
- ✅ Azure AI: Header passed through correctly
|
||||
- ✅ Bedrock Converse: Header filtered out (returns error without fix)

```
|
||||
|
||||
### Filtering Rules
|
||||
|
||||
1. **Header must exist in mapping**: Unknown headers are filtered out
|
||||
2. **Header must have non-null value**: Headers with `null` values are filtered out
|
||||
3. **Header transformation**: Headers are mapped to provider-specific names (e.g., `advanced-tool-use-2025-11-20` → `tool-search-tool-2025-10-19` for Bedrock)
|
||||
|
||||
### Example
|
||||
|
||||
Request with headers:
|
||||
```
|
||||
anthropic-beta: advanced-tool-use-2025-11-20,computer-use-2025-01-24,unknown-header
|
||||
```
|
||||
|
||||
For Bedrock Converse:
|
||||
- ✅ `computer-use-2025-01-24` → `computer-use-2025-01-24` (supported, passed through)
|
||||
- ❌ `advanced-tool-use-2025-11-20` → filtered out (null value in config)
|
||||
- ❌ `unknown-header` → filtered out (not in config)
|
||||
|
||||
Result sent to Bedrock:
|
||||
```
|
||||
anthropic-beta: computer-use-2025-01-24
|
||||
```
|
||||
|
||||
## Provider-Specific Notes
|
||||
|
||||
### Bedrock
|
||||
- Beta headers appear in both HTTP headers AND request body (`additionalModelRequestFields.anthropic_beta`)
|
||||
- Some headers are transformed (e.g., `advanced-tool-use` → `tool-search-tool`)
|
||||
|
||||
### Azure AI
|
||||
- Uses same header names as Anthropic
|
||||
- Some features not yet supported (check config for null values)
|
||||
|
||||
### Vertex AI
|
||||
- Some headers are transformed to match Vertex AI's implementation
|
||||
- Limited beta feature support compared to Anthropic

Centralized manager for Anthropic beta headers across different providers.
|

|

This module provides utilities to:
|
||||
1. Load beta header configuration from JSON (lists unsupported headers per provider)
|
||||
2. Filter out unsupported beta headers
|
||||
1. Load beta header configuration from JSON (mapping of supported headers per provider)
|
||||
2. Filter and map beta headers based on provider support
|
||||
3. Handle provider-specific header name mappings (e.g., advanced-tool-use -> tool-search-tool)
|
||||
|
||||
Design:
|
||||
- JSON config lists UNSUPPORTED headers for each provider
|
||||
- Headers not in the unsupported list are passed through
|
||||
- Header mappings allow renaming headers for specific providers
|
||||
- JSON config contains mapping of beta headers for each provider
|
||||
- Keys are input header names, values are provider-specific header names (or null if unsupported)
|
||||
- Only headers present in mapping keys with non-null values can be forwarded
|
||||
- This enforces stricter validation than the previous unsupported list approach
