Describe the bug I'm trying to visualize data from my Neptune DB using graph-explorer. I'm running graph-explorer in an EC2 instance within the same VPC as my Neptune cluster and creating an SSH tunnel from my local to port 8182 of this instance for connection. I can verify the connection by getting a response from https://<NEPTUNE_ENDPOINT>:8182/status from my browser.

However, the synchronization fails. The Network tab looks like the following

The first gremlin request gets a correct response but the second one fails with a 400. Additionally, the summary request fails due to a CORS error. Connectivity to the Neptune cluster is not a problem since the first gremlin request succeeds.

My graph has approximately 3,500 nodes and edges which I presume should not be large to cause timeouts.

• OS: Amazon Linux 2
• Browser: Google Chrome
• Graph Notebook Version: Built from current source
• Graph Database & Version: Amazon Neptune 1.2.1.0

Expected behavior A successful synchronization of the data.

@michaelnchin @triggan would you know how to go about this?

Is there any reason why you're looking to use an SSH tunnel versus the built-in proxy of Graph Explorer?

What are the details of the 400 error that is coming back on the subsequent requests?

Just realized you posted this in the graph-notebook repo. Graph Explorer is a different project: https://github.com/aws/graph-explorer

My bad, had multiple tabs open. Opening this in that repo. Thanks.
