Hi @Shaunak_Joshi !!
Welcome to our community 
Please, always fill in all the informations we ask in the template as those help us better understand your scenario.
You are probably using an outdated version of either the client and the server. Or maybe the model … 
Can you check that?
this is how you can get both using python v4 client:
print(weaviate.__version__, client.get_meta().get("version"))
The error message seems to be coming directly from Google.
Let me know if this help.
THanks!
