AWS_BEDROCK_LLM_REGION is required for AWS Bedrock.

Error message

AWS_BEDROCK_LLM_REGION is required for AWS Bedrock.

What it means

Configuration guard thrown by the AWSBedrockLLM constructor: the API key check passed but AWS_BEDROCK_LLM_REGION is empty/unset, so the client cannot determine which AWS region to send Bedrock requests to.

Solutions

1. Set the AWS_BEDROCK_LLM_REGION environment variable (e.g. us-east-1).
2. Configure the Bedrock region in provider settings.

When it happens

Trigger: Thrown at provider construction when AWS_BEDROCK_LLM_REGION is missing.

Common situations: AWS Bedrock selected without a region configured.
