Triton on Vertex AI does not support multiple models?

[ntranphong]

Currently, I want to deploy a Triton server to Vertex AI endpoint. However I received this error message.

"failed to start Vertex AI service: Invalid argument - Expect the model repository contains only a single model if default model is not specified"

Is this mean that the Triton server deploy only support one model? It is different from what I have read in this document about concurrent model execution
