Hi @hugo52,
thanks for the feedback. We can help if you would share a bit more details, the best would be to share the control panel screenshot that shows the groups.

In general, if you want to use bias and dark frames for all groups you simply need to add them to the session ensuring that they don't match the keyword you use to group flats and light frames, this allows you to use the same bias and darks for all groups that properly matches the exposure time and the binning.

Moreover, don't take warnings as errors, a warning is just information you need to pay attention to, but not necessarily you need to take actions against it. Sometimes a warning just informs you on WBPP's decisions on how to proceed with the calibration, If you are confident that your configuration is correct then go for it.

Hello, this answer is to easy, I spend meny hours to get it working.
warnings as light will not be calibrated are not good.
Flats wilt no bias or darks also.
Pls try a session with 5 days, using every day a separate flat and try to put it in a warnig free script or in a less importeand warning script.
I am sure that there is a big problem with this script and do not use it anymore.

I have a directory
NIGHT20210720 and inside that NIGHT20210720_Flat and NIGHT20210720_Light.
NIGHT20210717 and inside that NIGHT20210717_Flat and NIGHT20210717_Light.
the bias and darks are in a separated dir.
Keywords NIGHT20210720 and NIGHT20210717

Ok, you should name your folders "NIGHT_20210720" and "NIGHT_20210717", this is the correct keyword/value syntax to separate frames by NIGHT.

Use only "NIGHT" as keyword, the values assumed for the files under these folders will be "20210720" and "20210717" so light and flats will match these dates.
Moreover, you don't need to keep lights and flats separated in subfolders, you can save them under the corresponding folder for each night.

Keep the dark and bias out from these directories such that they will not be associated with any specific night. In such a way, they will be used to calibrate whatever group that matches the exposure (and binning) in any night.

This should work, let me know if you try!

Yes, that was the point.
Now i have warnings only from the flat who has no correct dark (so that is correct).
So, it is running now and i think the problem is solved.
But,,,, always a but, the manual of this script can be more clear.
Thank you for your help an i will updat this issue with the results.
Regards Hugo

The result after corrections, the old Batch preprocessing is performing about thesame.

Concerning the "manual" ...I really did try.
Please see:

(there are many sections, the ones that explain the keywords demonstrate what you are trying to do)
