Bug Description

Claude Code Will Not Switch to AWS Bedrock

Steps to Reproduce

mzagaja@TED-MBP-MZAGAJA ~/D/ai-reference> claude --version
1.0.76 (Claude Code)
mzagaja@TED-MBP-MZAGAJA ~/D/ai-reference> echo $CLAUDE_CODE_USE_BEDROCK
1
mzagaja@TED-MBP-MZAGAJA ~/D/ai-reference> echo $AWS_REGION
us-east-1
mzagaja@TED-MBP-MZAGAJA ~/D/ai-reference> claude -p 'Are you using AWS bedrock?'
No, I'm running through Anthropic's Claude API, not AWS Bedrock. Claude Code does support AWS Bedrock integration if you want to configure it to use Bedrock instead.

Expected Behavior

I expected Claude Code to use AWS Bedrock after set CLAUDE_CODE_USE_BEDROCK 1.

Actual Behavior

Claude Code used my Anthropic account.

Check /status to see if the Bedrock connection info is displayed. Also consider running with ANTHROPIC_LOG=debug to confirm your requests are indeed hitting Anthropic and not Bedrock.

I would say it is likely this has to do with Claude Code not properly seeing/inspecting the environment in fish shell. If I switch to zsh:

mzagaja@TED-MBP-MZAGAJA ~/D/ai-reference> zsh
mzagaja@TED-MBP-MZAGAJA ai-reference % export CLAUDE_CODE_USE_BEDROCK=1
mzagaja@TED-MBP-MZAGAJA ai-reference % export AWS_REGION='us-east-1'
mzagaja@TED-MBP-MZAGAJA ai-reference % claude

It works. This was not broken the other day, so I think its potentially a regression in newest update.

Just double-checking, can you confirm that you exported your env var via set -x CLAUDE_CODE_USE_BEDROCK 1? We don't do anything special around environment variable loading, which typically means the variable is not exported / visible to child processes like claude.

Also, consider using a settings.json.

mzagaja · 1 year ago

Ah, I was merely doing set CLAUDE_CODE_USE_BEDROCK 1 so -x seems to be significant here. Thanks for having me check that.
