Code using cp.rx.go works on Snippet editor, but not via cmdpost

[kaorukobo]

Here is a simple asynchronus programming script using the cp.rx.go package:

local Do = require "cp.rx.go.Do"

print "foo"
Do(function ()
    print "bar"
    return true
end):After(100)

The above snippet works on the Scripting Panel with the following output.

2024-03-30 16:47:28: foo
2024-03-30 16:47:28: bar

... but when I run the same with the cmdpost command,
it fails with "attempt to index a nil value" error before reaching the print "bar" line.

$ cmdpost sample.lua
foo

Does this qualify as a bug report? Or is there any mistake in my code?

Great question! I'm not sure about async operations via the command line tool.

Any ideas @cmsj or @asmagill?
