2. claude
3. any query

Expected Behavior

Additional Context

https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/overview#connect-to-amazon-bedrock
documentation precise we can override model (i'm in europe so 3.7 not yet available in eu-west-3) so i'm using 3.5. But got 400 status all the time.
On the other hand the documentation says "Claude Code requires access to both Claude 3.7 Sonnet and Claude 3.5 Haiku models, regardless of which API provider you use." So it's not clear to me if i can run claude code with 3.5 awaiting 3.7 availability in europe.
