I try initializing an llm, following an official tutorial in Colab: Get started with Gemma and LangChain. The tutorial instruct that I deploy a model from Model Garden and, when the endpoint is ready, copy its project ID, endpoint ID, and location, and enter them in Colab Cell like this:

I follow the instruction and collect three strings from the following places (as highlighted in yellow):

So, at this point the Colab cell that accept parameters look like this:

The problem arises when I run the model. Here is code from the cell in which the problem occurs and its traceback:

from langchain_google_vertexai import GemmaVertexAIModelGarden, GemmaChatVertexAIModelGarden

llm = GemmaVertexAIModelGarden(
    endpoint_id=endpoint_id,
    project=project,
    location=location,
)

output = llm.invoke("What is the meaning of life?")
print(output)

_InactiveRpcError                         Traceback (most recent call last)

     77         except grpc.RpcError as exc:

The above exception was the direct cause of the following exception:

InvalidArgument                           Traceback (most recent call last)

InvalidArgument: 400 Invalid Endpoint name: projects/use-gemma/locations/us-east1/endpoints/google_gemma-1_1-2b-it-mg-one-click-deploy.

Does anyone can spot what is the cause of the problem, and/or what have I done wrong? Thank you in advance for any help.
