Issue running Bison-@001 Model on my own Vertex AI set-up

Hi team and all, I am trying to run the L6 notebook on my own environment. I set-up google cloud, Vertex AI, API and after some iteration, everything is running well. Except when I go to the step where we take the closest stack overflow and try to compute the step :

from IPython.display import Markdown, display

t_value = 0.2
response = generation_model.predict(prompt = prompt,
temperature = t_value,
max_output_tokens = 1024)

I receive an error message : 400 Project XXX is not allowed to use Publisher Model projects/XXX/locations/europe-west9/publishers/google/models/text-bison@001 (XXX refer to my service account numbers).
Is text-bison@001 still supported on Vertex AI ? Or is there an issue with the zone I am using ? (I had no issue withe the previous step, namely the computation of Cosine similarity).

Many thanks !

Guillaume
