duplicate field error when setting a field to a function in an if/else

[BurninSun]

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

No duplicate field error

Actual Behaviour

  if x then
    t.s = function() return 1 end
  else
    t.s = function() return 2 end
  end

This is not a duplicate field and should not be an error

Reproduction steps

  if x then
    t.s = function() return 1 end
  else
    t.s = function() return 2 end
  end

Write that into the editor. See error as indicated above.

v3.6.4

Can confirm. Had to build out your example a bit, but the error message does indeed occur:

  local t = {}
  local x = true
  if x then
    t.s = function() return 1 end
  else
    t.s = function() return 2 end
  end

Also using VS Code (1.82.1) & the sumneko (v3.7.0) extension on Windows 11.
I have a @meta file with definitions for external APIs.
Is this the same problem?
I currently have the the inspection disabled by adding this before each @field that is flagged as duplicate:
--- @diagnostic disable-next-line: duplicate-doc-field
