Tried literally everything. Tried changing Api keys (Used Read, Write, Finegrained - with permissions). Tried changing models (TinyLlama, MetaLlama2, Deepseek)… Looked for other community posts… TRIED EVERTHING… Still ending with “Invalid credentials in Authorization header”

This is my original code:
from langchain_huggingface import ChatHuggingFace, HuggingFaceEndpoint
from dotenv import load_dotenv
import os

load_dotenv()

llm= HuggingFaceEndpoint(
repo_id=“TinyLlama/TinyLlama-1.1B-Chat-v1.0”,
task=“text-generation”,
huggingfacehub_api_token=os.getenv(“HUGGINGFACEHUB_API_TOKEN”)
)
print(“Loaded token:”, os.getenv(“HUGGINGFACEHUB_API_TOKEN”))

model = ChatHuggingFace(llm=llm)
model.invoke(“What is the capital of India?”) # Example usage

All required environments are installed.
Please help
