git config with multiple keys causes error "The value of SourceRoot.RepositoryUrl with identity is invalid"

I've multiple organization hosted on AzureDevOps and from the same machine i need to access with different identities to the repos of the different organizations
for this i've a config file in my ~/.ssh folder like this

```
Host vs-ssh.visualstudio.com
HostName vs-ssh.visualstudio.com
IdentityFile ~/.ssh/id_rsa
IdentitiesOnly yes

Host duke.vs-ssh.visualstudio.com
HostName vs-ssh.visualstudio.com
IdentityFile ~/.ssh/id_rsa_duke
IdentitiesOnly yes
```

as per microsoft's documentation [here](https://learn.microsoft.com/en-us/azure/devops/repos/git/use-ssh-keys-to-authenticate?view=azure-devops#q-how-do-i-use-different-ssh-keys-for-different-organizations-on-azure-devops)

i've cloned a repo using the host duke.vs-ssh.visualstudio.com

and now if i do
`git remote get-url origin`

i get
`photoatomic@duke.vs-ssh.visualstudio.com:v3/photoatomic/OrderProcessor/OrderProcessor`

**But** and when i compile i have the error

`The value of SourceRoot.RepositoryUrl with identity 'D:\OrderProcessor\' is invalid: 'ssh://photoatomic@duke.vs-ssh.visualstudio.com/v3/photoatomic/OrderProcessor/OrderProcessor' LillaKitchen.OrderPrinter, LillaKitchen.OrderProcessor, LillaKitchen.Xmenu.Order, MessageParser, PhotoAtomic.Printing C:\Program Files\dotnet\sdk\8.0.300-preview.24203.14\Sdks\Microsoft.SourceLink.AzureRepos.Git\build\Microsoft.SourceLink.AzureRepos.Git.targets 28`

if i change the remote url using

`git remote set-url origin photoatomic@vs-ssh.visualstudio.com:v3/photoatomic/OrderProcessor/OrderProcessor`

and compile, the error goes away (but obviously i cannot push anymore)

but i don't want to have to change the URL every time i want to compile or push

above the `C:\Program Files\dotnet\sdk\8.0.300-preview.24203.14\Sdks\Microsoft.SourceLink.AzureRepos.Git\build\Microsoft.SourceLink.AzureRepos.Git.targets `
Line 28
i've found this
```

```

Which makes me think i've to fill in my alternate domain somewhere.
can someone explain me how to use this? it is quite obscure to me
