[HELP] Unable to connect to Neptune Cluster

[KaylanHusband]

I've been trying to leverage this package to visually explore a Neptune graph and Im bumping into issues.

I've created an publically accessible EC2 instance within the Neptune VPC. I can ssh into it and telnet the Neptune cluster successfully.

For some reason I cannot synchronize the DB.

What could be causing this? Am I missing anything?

@KaylanHusband , does your Neptune cluster have IAM Db Auth enabled?

[KaylanHusband]

sudo docker run --rm -it okigan/awscurl
https://<neptune_endpoint>:8182/status
--access_key ***
--secret_key ***
--service neptune-db

@michaelnchin
Yes it does, and Im able to make sigv4 request through aws curl from the proxy as recommended here #127

I selected AWS IAM Auth Enabled

[michaelnchin]

Thanks for confirming.

We are aware of a bug currently affecting Graph Explorer connectivity to IAM enabled clusters, and have a fix pending: #140

We're planning to include the fix in an upcoming patch release, please stay tuned for updates.

@michaelnchin
When do you think these changes will be in? Is there another version I can use in the meantime?

[michaelnchin]

The fixes are now merged - we will have the formal release out later this week, but you should be now be able to pull and build the patched version via the setup documentation.

@michaelnchin

The issue is now resolved. Thanks!
