problem with anthropic claude haiku

in php when using the anthropic.claude-3-haiku-20240307-v1:0 model, it replaces the ":" with "%3A" which produces the error: Aws\BedrockRuntime\Exception\BedrockRuntimeException' with message 'Error executing "InvokeModel" on "https://bedrock-runtime.us-east-1.amazonaws.com/model/anthropic.claude-3-haiku-20240307-v1%3A0/invoke"; AWS HTTP error: Client error: POST https://bedrock-runtime.us-east-1.amazonaws.com/model/anthropic.claude-3-haiku-20240307-v1%3A0/invoke resulted in a 400 Bad Request response: {"message":""claude-3-haiku-20240307" is not supported on this API. Please use the Messages API instead."}

how can I solve that? The call I use is:

$path="anthropic.claude-3-haiku-20240307-v1:0";
  $bedrock = new Aws\BedrockRuntime\BedrockRuntimeClient(['region' => env('AWS_REGION', 'us-east-1'),'debug'=>true]);
            $result = $bedrock->invokeModel([
                'accept' => '*/*',
                'body' => $body,
                'contentType' => 'application/json',
                'modelId' =>($path)
                            //anthropic.claude-3-haiku-20240307-v1:0
            ]);
