Failed to add VM resource to Azure DevOps Environment

Question

I followed the steps to add a VM resource to an environment but got an error when running the script. I searched the error message but couldn't find anything.

Error messaege: Failed to add virtual machine resource. Linked environment pool is null.

The log file has these:

The config command is basically the following:

config --environment --environmentname DEV --agent computername --runasservice --work _work --url https://dev.azure.com/xxx/ --projectname myprojectname --auth PAT --token xxx

I am the org admin on DevOps and ran the script as server admin on the on-prem VM.

Update

After using the --unattanded option:

config --unattanded --disableloguploads --environment --environmentname DEV --pool org-agent-pool-nm --agent computername --runasservice --windowsLogonAccount xxx --windowsLogonPassword xxx --work _work --url https://dev.azure.com/xxx/ --projectname myprojectname --auth PAT --token xxx

I got a different error.

Flag 'unattended': 'True' 
Failed to add virtual machine resource. Linked environment pool is null.

Update 2

I found others are having the same or similar issues.
