lualib, couldn't find a container

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Firstly: I have seen #20371 but nut sure is the same reason or backgrounds....

Mostly when exporting pictures and dt started from console, I see this message:

ERROR in lualib, couldn't find a container for `scripts', this should never happen
ERROR in lualib, couldn't find a container for `face recognition', this should never happen
ERROR in lualib, couldn't find a container for `scripts', this should never happen

ERROR in lualib, couldn't find a container for `face recognition', this should never happen

I do not encounter problems so this is a minor issue IMHO

@wpferguson: per your request on IRC, here is the issue ;-)

Steps to reproduce

1. Having lua active and in my case face recognition module and others, face recognition has been used...
2. Go to lighttable
3. export one or several images
4. see the message

Expected behavior

Start with the lualib error path that reports missing containers, then reproduce the problem by launching darktable from the console and exporting images with Lua modules such as face recognition active. Use the attached logfile to compare the repeated messages with the export sequence; done means the underlying condition is fixed and the erroneous container warnings no longer appear.
