Issue with auto shutdown while looping multiple VMs

[nintendoMan]

Hi,

I have a purpose to set up auto shutdown schedules for multiple VMs....

resource vmInstances 'Microsoft.Compute/virtualMachines@2023-07-01' = [for i in range(1, numberOfVms): {
--- VM properties ---
}]

resource autoShutdownConfig 'Microsoft.DevTestLab/schedules@2018-09-15' = [for i in range(1, numberOfVms): {
name: 'shutdown-computevm-${vmPrefix}${i}'
location: location
properties: {
status: 'Enabled'
notificationSettings: {
status: 'disabled'
timeInMinutes: 15
notificationLocale: 'en'
emailRecipient: emailRecipient
webhookUrl: ''
}
dailyRecurrence: {
time: shutdownTime
}
timeZoneId: 'Fle Standard Time'
taskType: 'ComputeVmShutdownTask'
targetResourceId: vmInstances[i].id
}
dependsOn: [
vmInstances
]
}]

Exception Details:	(InvalidTemplate) Unable to process template language expressions for resource '/subscriptions/SUB-ID/resourceGroups/rg-A-avd-westeurope/providers/Microsoft.DevTestLab/schedules/shutdown-computevm-avd-vm1' at line '1' and column '8668'. 'The language expression property array index '1' is out of bounds.'

MY QUESTION IS:
There seems to be no way to implement via Bicep -> Auto shutdown plan via loops to multiple VMS?

I have trying to use this approach but no solution found.

Arrays start at 0. If you provide an array with a single element and start the iteration at index 1, you are doing the equivalent of trying to access the second element of an array of 1 element, explaining the out of bounds error.
