C4W2A2 Unable to Connect to EC2 to Generate Embeddings

I am unable to connect to the EC2 instance for 4.2.2. The error I’m getting is

Error: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[36], line 6
      4 # Performing API call and getting the result
      5 embedding_response = get_text_embeddings(endpoint_url=ENDPOINT_URL, text=text)
----> 6 embeddings = embedding_response['body']
      8 print(f"Text sent to the API: {text}")
      9 print(f"Length of the embedding from the response: {len(embeddings)}")

TypeError: 'NoneType' object is not subscriptable

I’ve tried rebooting the instance multiple times, as suggested in the notebook, but I’m still getting this error.

I also tried stopping and then restarting the instance. Same problem.

UPDATE: I was able to figure this out. The notebook loaded with some fields already filled out. At the beginning of the lab, there were some instructions to replace placeholder values with the RDS and EC2 endpoints. However, they were already filled out so I skipped that step. Can someone please look into why the notebook loaded with those values already filled out incorrectly?

Hi @yy55pl

Everything ok with the lab. It saves your previous attempts (everything that you changed in the lab.) It loads with the parameters that you (or someone else on your account) filled out before.
But AWS endpoints will be different after 2 hrs. It’s in the comment 2.1 of the lab.
