[Question]: How to remove environment agent if it is not visible in UI?

[eshmurus]

Describe your question

Our case: The resource (virtual machine) was manually deleted from the Azure DevOps Environment, and when try to create a new one with the same name, we get the error:

Failed to connect to xxx or execute command: Pool environment-xx- already contains an agent with name xxx_yyy

This agent/resource is not visible on UI, rest api doesn't return anything about it.
I tried --replace parameter, but it doesn't work for env agents.

Do you have any ideas?

Question closed: the agent can be fully removed here: https://your-organization.visualstudio.com/_settings/deploymentpools?view=pools
It's useful to add a few points to the documentation: do not manually remove the agent from the Environment, and if you have already done so, completely remove it from the Deployment Pools.
