Why aren't these two equivalent String() and variable as string

[Daniel-Kendall]

So I have an Array (userListAttach) of multiples links i.e. 

{
  "Name": "@{items('Apply_to_each')['name']}",
  "ContentBytes": "@{body('Get_file_content_using_path')}",
  "link": "@{items('Apply_to_each')['link']}"
}

To add as a property if I do:

variables('userListAttach')?[0]?['link'] after initialising a string variable it works.


HOWEVER if I do:

string(variables('userListAttach')?[0]?['link'])

it fails.

Why?!

Hi @Daniel-Kendall 

What error you getting using this expression?

string(variables('userListAttach')?[0]?['link'])

Variable 'userListAttach' is already a string? Believe you already declared that as a variable so why you need to convert to string again?

A screenshot of your flow will be helpful to analyse?

Thanks

userListAttach is an Array.
It contains multiple 'links' keys I want to treat the value of as strings to pass as a URL to sharepoint.
if I do:
variables('userListAttach')?[0]?['link'] after initialising a string variable it works.
HOWEVER if I do:
string(variables('userListAttach')?[0]?['link'])

It wasn't working

Weird it is working now, I just flan the flow again.
