I have deployed my App on Vertex AI endpoint. The endpoint is created successfully and I am getting "Active" status. But when I try to invoke the endpoint, I am getting the following error:

{ "error": { "code": 500, "message": "Prediction failed. Please contact cloudml-feedback@google.com", "status": "INTERNAL" } }

POST Request URL: https://us-central1-aiplatform.googleapis.com/v1/projects/${PROJECT_ID}/locations/us-central1/endpoints/${ENDPOINT_ID}:predict

Header: I am passing the required header i.e., Content-Type: application/json and Authorization token.

Body: { "instances": [{ "image_path": "https://github.com/naqishah13/multilabelimages/blob/main/movie-poster-1.jpg?raw=true" } ] }

Here is my flask code that I am using for prediction:

@app.route('/get_movie_genres/', methods=['POST'])
def main():
    request_json = request.get_json()
    request_instances = request_json['instances']
    image_path = request_instances[0]['image_path']
    predicted_genres = predict_(image_path)
    output = {'predictions':
               [
                   {
                       'predicted_genres' : prediction
                   }
               ]
           }
    return jsonify(output)

I have saved some images on Github and I am using those images (via Github path) in order to do the movie genre prediction.

Kindly let me know if I am doing something wrong and what might be causing the issue.

What I have tried:

I have tried invoking the endpoint using curl command, but still I am getting the permission related errors even though I have provided the authentication correctly.
