I’m getting this cryptic error code. I specified a role with the DescribeInstances permissions in the scrape config file… When running this command,
./promtail-linux-amd64 -config.file=./ec2-promtail.yaml --dry-run
I get this error

For ease of reading, it goes something like this:
<ErrorResponse “http://webservices.amazon.com/AWSFault/200. Sender. InvalidAction. <|Message>Could not find operation DescribeInstances for version 2. . | 2bbe..caused by: expected element type but have ”
Is this a bug or is the configuration wrong
