Thank you all so much for offering to help. Here's my project structure (very simple): agent.py import os from dotenv import load_dotenv from google.adk import Agent load_dotenv() root_agent = Agent( name="transcript_summarization_agent", description="Summarizes chat transcripts.", model=os.getenv("MODEL", "gemini-2.5-flash"), instruction="Summarize the provided chat transcript.", ) .env: GOOGLE_GENAI_USE_VERTEXAI=TRUE GOOGLE_CLOUD_PROJECT=basic-ai-agent-471801 GOOGLE_CLOUD_LOCATION=us-central1 MODEL=gemini-2.5-flash Here's the error it gives: {"error": "Your default credentials were not found. To set up Application Default Credentials, see https://cloud.google.com/docs/authentication/external/set-up-adc for more information."} It works fine if I set GOOGLE_GENAI_USE_VERTEXAI=FALSE and supply GOOGLE_DEFAULT_CREDENTIALS=<my API key> Can you please help?

@Purendeeswar Reddy Thanks for your response. If I generate a SA Json Key, how should that be used in the agent.py code?
