Bug Description

Unable to use bedrock , it was working a few days ago.

Steps to Reproduce

I tried

ANTHROPIC_MODEL='us.anthropic.claude-3-7-sonnet-20250219-v1:0' \

CLAUDE_CODE_DEBUG=1 \
AWS_REGION_NAME='us-west-2' \

╰─────────────────────────────────────────────────────────────╯

> /init is analyzing your codebase…
  ⎿  API Error: 403 You don't have access to the model with the specified model ID.

I then try to use full arn for inference profile, now claude returns a different error message

ANTHROPIC_MODEL='arn:aws:bedrock:us-west-2::inference-profile/us.anthropic.claude-3-7-sonnet-20250219-v1:0' \
CLAUDE_CODE_USE_BEDROCK=1 \
AWS_REGION_NAME='us-west-2' \
AWS_DEFAULT_REGION='us-west-2' \
claude

I have the same issue.

This issue occurs when there is a mismatch with the AWS_REGION and/or the incorrect cross-region inference profile ids are used (or not activated in the region you think they are activated).

Enable model access in the correct region in the AWS Console: Amazon Bedrock > Model access
Use Inference profile IDs from: Amazon Bedrock > Cross-region inference

Examples of valid parameters to run Claude Code:

AWS_REGION='us-east-1' ANTHROPIC_MODEL='us.anthropic.claude-3-5-sonnet-20241022-v2:0' ANTHROPIC_SMALL_FAST_MODEL='us.anthropic.claude-3-5-sonnet-20241022-v2:0' CLAUDE_CODE_USE_BEDROCK=1 CLAUDE_CODE_DEBUG=1 DISABLE_PROMPT_CACHING=1 claude

AWS_REGION='eu-west-1' ANTHROPIC_MODEL='eu.anthropic.claude-3-7-sonnet-20250219-v1:0' ANTHROPIC_SMALL_FAST_MODEL='eu.anthropic.claude-3-5-sonnet-20240620-v1:0' CLAUDE_CODE_USE_BEDRO CK=1 DISABLE_PROMPT_CACHING=1 CLAUDE_CODE_DEBUG=1 claude

@md-ae thanks that's helpful. I have aws_region configured in aws cli, but did not expect to set the AWS_REGION env

@yangcheng hopefully the AWS_REGION env var resolved this for you! Please reply if you're still running in to this issue.
