Hello, dear Hans.

I have a Lua module that doesn't work in the latest version 2024.08.16
16:30. After investigation,
I found that the errors first occurred in the appendaction. It could be appended
normally in the version 2024.04.01 08:59, but failed in the latest version. So,
I made a minimum runnable example for the appendaction problem,
mini-try.lmtx, as

```ConTeXt
\startluacode
Moduledata = Moduledata or {}
Moduledata.vtypeset = Moduledata.vtypeset or {}

function Moduledata.vtypeset.rotate_all1(head)
    print(">>>>>> HERE IS ROTATE_ALL1")
    return head, done
end

function Moduledata.vtypeset.rotate_all2(head)
    print(">>>>>> HERE IS ROTATE_ALL2")
    return head, done
end

nodes.tasks.appendaction("processors", "after",
"Moduledata.vtypeset.rotate_all1")
nodes.tasks.appendaction("shipouts", "after",
"Moduledata.vtypeset.rotate_all2") -- fails here

\stopluacode

\starttext

try

\stoptext
```

Compiled the mini-try.lmtx and got outputs in terminal:

```

My question is: Can I still appendaction in "shipouts" "after"? If so,
how to do it?

Best regards,
