Failed luau to rust type conversions on a few argument cases with `process.spawn`

Code used:
local success, result = pcall(function()
local spawnResult = process.spawn("ffmpeg", '--dry-run', 'cmd', "inherit")
end)
print(success, result)
When trying to spawn a process using any value except for nil
for the 3rd shell argument, an error like this will be raised:
Failed to convert Luau type 'string' into Rust type 'table'!
[Stack Begin]
Script '[C]'
Script 'async', Line 2 - function process.spawn
Script '../test', Line 9
Script '[C]' - function pcall
Script '../test', Line 8 - function convert
Script '../test', Line 49
Script '[C]' - function pcall
Script '../test', Line 42
[Stack End]
This same issue also happens if the 2nd argument is set to an empty string ''
:
local spawnResult = process.spawn("ffmpeg", '', nil, "inherit")
Error message:
Failed to convert Luau type 'string' into Rust type 'Vec'!
Details:
expected table

Nevermind. The issue actually stems from me misreading the type annotation of the 2nd argument of process.spawn. Sorry for the wasted time 😅
