Bad Request When deploying an Azure Kubernetes Service (Error parsing provided IP..... Invalid resource Id format...)

[anthony-c-martin]

Thanks for reporting. We'll follow up with the AKS team, as the error is coming back from the RP during the validation stage.

@anthony-c-martin while the error does come back from the AKS RP, that's because the value that's being submitted for a public IP object ID is the string [reference(resourceId('Microsoft.Resources/deployments', format('{0}-pip', parameters('name'))), '2019-10-01').outputs.id.value] - for whatever reason, it's not being resolved to a resource ID before the call to our RP.

Use of the reference() function cannot be resolved during the validation phase. The RP is supposed to skip over any checks for values that have an unresolved expression like this, but the RP is not doing that right now, which is what the AKS team needs to fix. I will follow up with the AKS team.

@phealy - here's the relevant ARM documentation on preflight implementation: https://armwiki.azurewebsites.net/api_contracts/preflight.html - see the note on "Template Language expressions".

@anthony-c-martin thank you, I understand the issue now. I've updated an AzDO bug with this use case and asked for it to be looked at.

It's been two years since the last update. Is this bug still active?

[anthony-c-martin]

@phealy could you confirm whether this has been fixed?
