Can't use conditional statement for resource(serviceBus/namespaces/queues) parameters

[marcincakA]

Bicep version 0.27.1

Describe the bug Can't use conditional statement for resource(serviceBus/namespaces/queues) parameters (Error BCP053: The type "object" does not contain property "sessions". Available properties include "name".)

To Reproduce See provided file

Additional context This type of condition [line 37 -> contains(queue, 'sessions') ? queue.sessions : false] works fine when used for parameter of bicep module mainArrayIssue.zip

I have similar problem but with sort function, here's a repro:

var items = [
  { obj: 1 }
  { obj: 2 }
  { obj: 3 }
  { obj: 4 }
  { obj: 5
    x: 5
  }
]
var s = sort(filter(map(items, x => x.obj < 2 ? { order: 1, value: x } : x.obj > 4 ? { order:2, value: x} : {}), x => !(empty(x))), (arg1, arg2) => arg1.order < arg2.order)

This was working in 0.26.70, so I think this is a bug in 0.27.1

The error I get is Argument of type "((object | object | object), (object | object | object)) => error" is not assignable to parameter of type "(any, any) => bool".bicep(BCP070)

Here is another issue that may be related

Error message Error BCP052: The type "object" does not contain property "Value"

Here the error stems from the condition used inside the array variable (line 13)

Without the condition it works mainConditionInArray.zip 114-9970-1db4fd2f5cfe)

In both cases, I believe the issue is that type validation isn't smart enough to figure out that you're excluding the base case with the check for empty()

@miqm not the most elegant solution, but a temporary workaround could be to wrap with any():

var items = [
  { obj: 1 }
  { obj: 2 }
  { obj: 3 }
  { obj: 4 }
  { obj: 5, x: 5 }
]
var s = sort(
  filter(
    map(items, x => x.obj < 2 ? { order: 1, value: x } : x.obj > 4 ? { order: 2, value: x } : {}),
    x => !(empty(x))
  ),
  any((arg1, arg2) => arg1.order < arg2.order)
)

@marcincakA a workaround for your scenarios would be to use the .? operator:

queue.?sessions ?? false

[miqm]

yeah, I managed to find place to put any. anyway, would be good to not to have it.

Partially that's true, but even if remove filter and put a question mark on the order property, bicep still complains:

Ah I think I see the problem - I believe introduced with #14017.

Here's a minimal repro:

param foo string
param index int

var test = [
  { foo: foo }
  { }
][index]

output val string = test.foo

@marcincakA if you get a chance, please could you verify whether #14060 fixes the problem for you?
