Bedrock Batch Inference with Claude

Hi,

I have been using bedrock batch inference for a while, despite being in preview it seems to typically work most of the time. However I have recently tried using batch inference with Claude 3 in the eu-west-2 region and I am getting the following error:

botocore.errorfactory.ValidationException: An error occurred (ValidationException) when calling the CreateModelInvocationJob operation: The provided request is not valid

Unfortunately it doesn't tell me which part of the request is not valid. When making the exact same request to Claude 3 in the eu-west-3 and us-east-1 region it works perfectly still. I am also getting the same error when calling batch inference on Claude3.5 in the us-east-1 region.

Are some models disabled for batch inference? Or has there been an API update that hasn't been rolled out across all regions? Is anyone else able to get Bedrock Batch Inference working with Claude 3 in eu-west-2 or Claude 3.5 in us-east-1?

Any help would be great.
