userIdentity = '/subscriptions/555-555-555-555-555-555/resourcegroups/fake/providers/Microsoft.ManagedIdentity/userAssignedIdentities/Fakeidentity';

automationIdentity = '/subscriptions/555-555-555-555-555-555/resourcegroups/fake/providers/Microsoft.ManagedIdentity/userAssignedIdentities/Fakeidentity2';

new azure_native.compute.VirtualMachineScaleSet(vmssname,{

identity: {

type: "UserAssigned",

userAssignedIdentities:{ userIdentity: {},

automationIdentity: {},

}},

Here's the error I get: 
azure-native:compute:VirtualMachineScaleSet (vmssname):
  error: Code="LinkedInvalidPropertyId" Message="Property id 'automationIdentity' at path '' is invalid. Expect fully qualified resource Id that start with '/subscriptions/{subscriptionId}' or '/providers/{resourceProviderNamespace}/'.

Nevermind solved it, I had to write the literal with this syntax:

        userAssignedIdentities:{ [`${automationIdentity}`]: {},
                                 [`${envIdentity}`]: {},

primary: {
   all my primary stuff 
}
secondary: {
 all my secondary stuff
}

primary

secondary

stack.Output('primary.something')

error: Error: Cannot call 'getOutputValue' if the referenced stack output is a secret. Use 'getOutput' instead.
