Neptune Notebooks and Graph Explorer Fail to Launch

Question

When trying to launch Juptyer, Jupyter Lab, Graph Explorer, Start, Stop or Delete Neptune Notebooks with the Status of 'Ready', I'm blocked by a pop-up disclaimer stating:

"Notebook status must be Ready while the current status is undefined"

I have rebooted, started, stopped these instances connected to the notebooks, gone into Sagemaker and started, stopped these notebooks, created new DB Clusters and instances w/ notebooks, to no avail.

Is there a solution to this problem? If this is simply a UI bug, is there any other way to access Graph Explorer?

Accepted Answer

This is a bug that we also discovered early this morning. A fix has been submitted and is currently rolling out to all regions.

To access Graph Explorer, for now, go to the SageMaker console and open the Notebook instance as if you're opening it to use Jupyter.  After Jupyter is open, change the URL to:

```
https:///proxy/9250/explorer/
```

That should open Graph Explorer.

Answer

I tried this, and it does boot into Graph Explorer, but I'm now stuck in a loop where its asking me to synchronize my database, then fails everytime.
