Unable to connect to SageMaker notebook on AWS

[chris-merapar]

Bug: Notebook Editor

Steps to cause the bug to occur

1. Start an AWS Sagemaker notebook instance
2. Use the AWS CLI command "aws sagemaker create-presigned-notebook-instance-url" to get a presigned notebook instance URL
3. Rename the URL param "authToken" to "token" from step 2, otherwise VSCode will ask you to enter a password when it connects
4. In VSCode, select Python: Specify local or remote jupyter server..." from command palette and give the URL
5. Try to run a notebook in VSCode

Actual behavior

Connection fails with "Error: Invalid response: 200 OK"

Extra debug info:
Connecting to local instance of Jupyter notebook works ok. Comparing the Sagemaker notebook URL and the localhost notebook URL in Postman reveals the responses are very similar. Using both local and Sagemaker URLs, the /api/status path works fine and returns the same output.

Expected behavior

Connection should succeed.

@chris-merapar Thanks for reporting this issue and for providing this log. So I believe that you mentioned this already, but if you take the exact same URL that you put into VSCode you are able to paste it into a web browser on your vscode machine and connect to the jupyter instance via the browser? Our vscode setting will only work on something that directly works that way. I'm not fully sure on this, but it looks like that url link might be redirecting, which I don't believe our code would handle. In a redirect case the browser might be able to work, but we might fail. I see the initial setting here:

https://xxxx-test.notebook.eu-west-1.sagemaker.aws/

But later on in the log I'm seeing it resolve to a different url:

{ url: 'https://console.aws.amazon.com/sagemaker/home?region=eu-west-1&notebookState=L2FwaS9jb250ZW50cy8%3D#/notebook-instances/openNotebook/xxxx-test', status: 200, statusText: 'OK',

That second URL doesn't look like something we could connect to.

[chris-merapar]

Yes you are correct, AWS authorises the request and then sets a cookie and redirects. But when I do this in Postman (which follows the redirect) the end result after redirect looks the same as the locally hosted notebook URL. Which part specifically will not work with VSCode, is it the redirect or setting the cookie and expecting to see it in subsequent requests? I am considering making a proxy that works around whatever the incompatibility is.

Edit: It appears AWS works this way as they don't want to expose ports on Sagemaker directly or use the Jupyter auth scheme, they want to proxy everything and use their own auth mechanisms for greater flexibility.

[IanMatthewHuff]

Yeah, that was what I was figuring was going on. We can discuss this at our triage, but it's not something that we can support right now from our side. Jupyter does have the concept of a session cookie to validate a session. Is that the cookie that AWS is sending, or is it something AWS authorization specific? We do handle jupyter session cookies when we do a password connect. So there might a possibility that we could allow for a users to input a validated cookie somehow.

Curious if there are any updates on this issue. Thanks.

Triage: Is #1057 a dupe of this issue?

[greazer]

This is a specific issue relating to supporting AWS. We will consider at a later time.

[KiraPC]

Any news about this issue? I'm trying to connect to AWS Sagemaker Notebook without success.

Closing in favour of #12268
