Could not load the embeddings engine to get the dimensions. Please check the configuration.Error executing "InvokeModel" on "https://bedrock-runtime.us-east-1.amazonaws.com/model/amazon.titan-embed..."; AWS HTTP error: Client error: `POST https://bedrock-runtime.us-east-1.amazonaws.com/model/amazon.titan-embed...` resulted in a `400 Bad Request` response: {"message":"Malformed input request: #: only 1 subschema matches out of 2, please reformat your input and try again."} ValidationException (client): Malformed input request: #: only 1 subschema matches out of 2, please reformat your input and try again. - {"message":"Malformed input request: #: only 1 subschema matches out of 2, please reformat your input and try again."}
When I try to create a server using AWS Bedrock and Milvus I get the above error. I'm trying to use the Titan Text Embeddings V2 (amazon.titan-embed-text-v2.0) model.
Is this really happening because the formatInput method in TitanEmbeddings.php lists amazon.titan-embed-text-v1 in it?
If I change it to v2 the error goes away and I can index things into Milvus.
public static function formatInput($input = "", $image = NULL, $config = [], $model_id = '') {
if ($input) {
$payload['inputText'] = $input;
}
elseif ($image && strpos($model_id, 'amazon.titan-embed-image') === 0) {
$payload['inputImage'] = $image->getAsBase64EncodedString('');
}
else {
throw new AiBadRequestException('You need to give an input text or an image or you used as image in a none-image embeddings model.');
}
if (strpos($model_id, 'amazon.titan-embed-image') === 0) {
$payload['embeddingConfig']['outputEmbeddingLength'] = (int) $config['outputEmbeddingLength'];
}
elseif (strpos($model_id, 'amazon.titan-embed-text-v2') !== 0) {
$payload['dimensions'] = (int) $config['dimensions'];
}
return $payload;
}

I've just run into this as well, it would be good to get this committed if we no longer need to support v1. Otherwise we might need to alter the if statements to check both v1 and v2.
I wonder if we can turn these into plugins or do something a little nicer than elseifs checking strings. But I think thats something to think about later.
