Set the platform to 64 bit in ARM template

Question

I have the following arm template:

resource functionApp 'Microsoft.Web/sites@2018-02-01' = {
  name: name
  location: location
  kind: kind
  properties: {
    serverFarmId: resourceId('Microsoft.Web/serverfarms', servicePlanName)
    clientAffinityEnabled: false
    httpsOnly: true
    siteConfig: {
      appSettings: secretSettings
    }
  }
  identity: {
    type: 'SystemAssigned'
  }
}

I need to set the platform to 64 bit. On updating this to:

resource functionApp 'Microsoft.Web/sites@2018-02-01' = {
  name: name
  location: location
  kind: kind
  properties: {
    serverFarmId: resourceId('Microsoft.Web/serverfarms', servicePlanName)
    clientAffinityEnabled: false
    httpsOnly: true
    siteConfig: {
      appSettings: secretSettings
      use32BitWorkerProcess : false
    }
  }
  identity: {
    type: 'SystemAssigned'
  }
}

I see it failing. What am I missing?

As you have not shared any error details , So there is only solution As the MS DOC provided by @evgeny, you can use the below template and deploy it as well. for example:-

use32BitWorkerProcess : bool // If need to enable 64 , provide false as value
