unexpected type mismatch: expected String, found Record([])

[N4tus]

Describe the bug

def provideStr [r: record] {
  "test"
} 

def needStr [str: string] {
  echo $str
}

def run [r: record] {
  needStr (provideStr $r)
}

run {a:b}

This script errors with:

Error: nu::parser::type_mismatch (link)

  × Type mismatch.
    ╭─[/d/dev/nu/test.nu:9:1]
  9 │ def run [r: record] {
 10 │   needStr (provideStr $r)
    ·           ───────┬───────
    ·                  ╰── expected String, found Record([])
 11 │ }
    ╰────

But provideStr does return a string. Putting the expression around quotes ((provideStr $r) -> $"(provideStr $r)") solves this issue but it looks unnecessary.
The more curious case is, that r has to be a parameter and not a variable. This script runs just fine:

def provideStr [r: record] {
  "test"
} 

def needStr [str: string] {
  echo $str
}

let r = {a:b}
needStr (provideStr $r)

How to reproduce

1. create a file named test.nu with the content:

def provideStr [r: record] {
  "test"
} 

def needStr [str: string] {
  echo $str
}

def run [r: record] {
  needStr (provideStr $r)
}

run {a:b}

2. run it with nu test.nu

Expected behavior

I expect nu to use the output from provideStr as positional parameter for the needStr command.
