Description

I run a set of userdata commands to spin up Graph Explorer in an EC2.
Auth is via IAM auth and EC2 have the necessary IAM role attached. 

#!/bin/bash
cd /home/ec2-user
TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` 
EC2_IP=$(curl -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/meta-data/public-ipv4)
EC2_HOSTNAME="https://"$EC2_IP
echo $EC2_HOSTNAME
yum update -y
yum install git docker -y
git clone https://github.com/aws/graph-explorer/
systemctl start docker
docker buildx build graph-explorer -t "graph-explorer" 
docker run -p 80:80 -p 443:443 --env HOST=$EC2_HOSTNAME --env PUBLIC_OR_PROXY_ENDPOINT=$EC2_HOSTNAME --env GRAPH_TYPE=gremlin --env USING_PROXY_SERVER=true --env IAM=true --env AWS_REGION=us-east-1 --env GRAPH_CONNECTION_URL=https://[redacted].us-east-1.neptune.amazonaws.com:8182 --env PROXY_SERVER_HTTPS_CONNECTION=true --env GRAPH_EXP_FETCH_REQUEST_TIMEOUT=240000 graph-explorer

This setup has been working well for months but recently it started to fail with this error:

[01:57:58.914] ERROR (40): Could not load credentials from any providers

      "type": "CredentialsProviderError",

      "name": "CredentialsProviderError",

    }

Graph Explorer could not synchronise with Neptune Database as a result.

Environment

Expected Behavior

To use IAM auth from EC2 and connect to Neptune Database.

Got it to work again if i update my EC2 Instance to run on imds v1 and v2. If only v2 is allowed, this will break.

Can this be fixed please?
