Hi,  
Below is the POST method I added:  
@app.route(‘/greet’, methods=[‘POST’])  
def greet():  
“”"  
Handles POST requests to the /greet endpoint.  
Expects JSON data with a ‘name’ field.  
“”"  
data = request.get\_json()  
if data and ‘name’ in data:  
name = data[‘name’]  
return jsonify({“message”: f"Hello, {name}!"}), 200  
else:  
return jsonify({“error”: “Invalid request. Please provide ‘name’ in JSON data.”}), 400

Getting the error code 404 and text response as ‘Cannot POST /spaces/name/space/v1/greet’

Hmm… Like this issue?

> Hello everyone, I’ve deployed a FastAPI application on Hugging Face Spaces. Everything seems to be running smoothly, and there are no errors in the logs. However, when I try to access my endpoints via a browser or tools like Postman, I’m getting a “404 error” or a “Cannot POST” error. Here’s a brief overview of my setup: I have a FastAPI route defined as @app.get("/check\_request") and another one as @app.post("/recommend"). My Dockerfile specifies the CMD as CMD ["uvicorn", "app:app", "--hos…

Throw this in there to help you debug a bit better.  
if data and ‘name’ in data:  
name = data[‘name’]  
return jsonify({“message”: f"Hello, {name}!"}), 200  
else:  
return jsonify({“error”: “Invalid request. Please provide ‘name’ in JSON data.”}), 400

The frontend or client is POSTing to a different path or the data is in a bad format and you aren’t grabbing name.

Try a curl on the api to test it as well.
