I'm trying to setup EC2 Instance Connect to RDP to a Windows server.

I'm running the command like so...

aws ec2-instance-connect open-tunnel \
    --instance-id <my-instance-id> \
    --remote-port 3389 \
    --local-port 33389

The command immediately exits, displaying only...

'VpcId'

No other errors are shown. I don't even know where to start to debug this. The response is meaningless.

I've confirmed that the cli is connecting to the correct AWS account. As far as I can see the IAM user has the correct permissions.

The Instance Connect endpoint works from the AWS console.

My aws cli version is...

aws-cli/2.17.20 Python/3.11.9 Linux/5.15.153.1-microsoft-standard-WSL2 exe/x86_64.ubuntu.22

I've tried running the cli command with the --debug option. This is the final part of the output...

I found the problem. The instance had been terminated. I'd copied the wrong Id ‍♂️

Anyway I'll leave this, just in case it's helpful for anyone else. The error was very confusing.
