Other Notes

https://github.com/Azure/azure-quickstart-templates/blob/master/quickstarts/microsoft.compute/vmss-automatic-repairs-slb-health-probe/azuredeploy.json#L257

All the variations below, which are show in the docs above, get translated to this in the deployed arm template:
"networkProfile": {
"healthProbe": "[reference(resourceId('Microsoft.Network/loadBalancers', variables('lbName')), '2024-01-01').probes[1].id]",

Error in azure deployment: "Value for reference id is missing. Path Properties.UpdateGroups[0].NetworkProfile.healthProbe."

The warning shown by the linter: The property "healthProbe" expected a value of type "ApiEntityReference | null" but the provided value is of type "string".

Bicep Repro

networkProfile: {
healthProbe: lb.properties.probes[1].id
//'${lb.id}/probes/${lbProbeName443}'
//resourceId('Microsoft.Network/loadBalancers/probes', lbName, lbProbeName443)

Confirm

• I have read the troubleshooting guide and looked for duplicates.

Start with the linked azuredeploy.json around line 257 and compare its healthProbe reference with the Bicep repro and the linked Azure documentation. Confirm the expected reference-id shape and verify that the deployment no longer reports a missing reference id or the linter type warning.
