ColumnSpan : Array to string conversion

Hello everyone, Is it only me who has this problem when I try to make my columns dynamic on any of my fields, I get the following error if I try to return an array from a closure: Array to string conversion Here is my code: 
->columnSpan(function($get) {
  return $get('show_time') ? [
      'default' => 12,
      'sm' => 12,
      'md' => 3,
      'lg' => 3,
      'xl' => 3,
      '2xl' => 3,
  ]:[
      'default' => 12,
      'sm' => 12,
      'md' => 9,
      'lg' => 9,
      'xl' => 9,
      '2xl' => 9,
  ];
})
->columnSpan(function($get) {
  return $get('show_time') ? [
      'default' => 12,
      'sm' => 12,
      'md' => 3,
      'lg' => 3,
      'xl' => 3,
      '2xl' => 3,
  ]:[
      'default' => 12,
      'sm' => 12,
      'md' => 9,
      'lg' => 9,
      'xl' => 9,
      '2xl' => 9,
  ];
})
Whereas if I pass it an array directly without closure, I have no error. Is this a bug? Or am I the only one getting this problem?

What is $get(‘show_time’) returning? If it’s anything other than true/false/null it will break your ternary.

it's a Toggle and it returns true or false. I have the same error with : 
->columnSpan(fn() => [
      'default' => 12,
      'sm' => 12,
      'md' => 9,
      'lg' => 9,
      'xl' => 9,
      '2xl' => 9,
  ]),
->columnSpan(fn() => [
      'default' => 12,
      'sm' => 12,
      'md' => 9,
      'lg' => 9,
      'xl' => 9,
      '2xl' => 9,
  ]),
and not error with : 
->columnSpan([
      'default' => 12,
      'sm' => 12,
      'md' => 9,
      'lg' => 9,
      'xl' => 9,
      '2xl' => 9,
  ]),
->columnSpan([
      'default' => 12,
      'sm' => 12,
      'md' => 9,
      'lg' => 9,
      'xl' => 9,
      '2xl' => 9,
  ]),
So it's not the condition but I think it's the Closure...

Sorry. Not sure then. Your code looks correct and the columnSpan method accepts a closure. Is this in a resource or a stand alone form.

In a stand alone form, I tested in multi forms and I have the same error. Can you try in your app if this code on any field returns an error? 
->columnSpan(fn() => [
      'default' => 12,
      'sm' => 12,
      'md' => 9,
      'lg' => 9,
      'xl' => 9,
      '2xl' => 9,
  ]),
->columnSpan(fn() => [
      'default' => 12,
      'sm' => 12,
      'md' => 9,
      'lg' => 9,
      'xl' => 9,
      '2xl' => 9,
  ]),
I suspect a code bug in Filament or my entire application... Thank's for help!

Make sure you are calling $this->form->fill() in the mount() method
