Loading VertexAIEmbeddings is stuck

Gemini API
1

This is my code;

from langchain_google_vertexai import VertexAIEmbeddings
self._embeddings = VertexAIEmbeddings(
    model_name="text-embedding-004"
)

It works well in my local dev env(Docker). But in my production env(GKE, Kubernetes), it stuck on below line intermittently ;

self._embeddings = VertexAIEmbeddings(
    model_name="text-embedding-004"
)

As it works from time to time, I don’t think it’s an auth issue. Does anyone got a similar issue?
