API Error: Truncated event with using Bedrock Inference Profiles

[lou-k]

Bedrock Application Inference profiles are a great way to track costs between different applications in the same aws account.

Unfortunately, claude code seems to choke when using one :(.

ANTHROPIC_MODEL="arn:aws:bedrock:***:****:application-inference-profile/***" claude --verbose --debug -p hello
 API Error: Truncated event message received.

Is it easy/possible to support these? I assumed the response from bedrock would be the same shape :*(.

Having the same issue.

I think the issue has to do with escaping the ARN - you need to switch the / in the ARN to %2F:

CLAUDE_CODE_USE_BEDROCK=1 DISABLE_PROMPT_CACHING=1 ANTHROPIC_MODEL="arn:aws:bedrock:us-east-1:xxx:application-inference-profile%2Fxxx"

Doing this resolved the issue for me. I opened anthropics/anthropic-sdk-typescript#715 in the underlying library to try to fix more automatically.
