looking like it is related the the scope I am using it in

[bashor]

Please provide more info. Ideally, a self-contained example.

[bashor]

maybe compiler diagnostic as is

What is textContent and client?

[trevjones]

XMLHttpRequest().also { client ->
  client.open("GET", logcatFile)
  client.onreadystatechange = { event ->
    logcatArea.textContent = client.responseText
  }
  client.send()
}

where logcatArea is of type Element

[trevjones]

even if I say logcatArea.textContent = "foo" inside that callback it complains the same. just outside and everything is fine. wondering if it is some sort of closure of variable entity type of issue?

[trevjones]

looking like the following might do what I need:

window.fetch(Request(logcatFile)).then {
  it.text().then {
    logcatArea.textContent = it
  }
}

[bashor]

try to write anything in next line

[bashor]

e.g. Unit or null

[trevjones]

yup that solves it

[bashor]

window.fetch(Request(logcatFile)).then {
  it.text().then {
    logcatArea.textContent = it
    null
  }
}

return of callback expecting something and result of assignment is what void/Nothing?

yes, compiler expected that callback will return anything, but assignment is not expression in Kotlin and compiler doesn’t know where from take a value to return
