Encountered error in module: 
CreateCalibrationDetails

Error message:
java.lang.NullPointerException

Cause:
null
bV.a(Unknown Source)
bV.doInBackground(Unknown Source)
javax.swing.SwingWorker$1.call(SwingWorker.java:295)
java.util.concurrent.FutureTask.run(FutureTask.java:266)

Process:

Load session 1 lights as Session 1

Load session 2 lights as Session 2

Load BPM and Master Dark

Load MF and MDF from session 1 (done previously) as Session 1

Load MF and MDF from session 2 (done previously) as Session 2

Assign Masters to Lights

I also get the error if I don't use previously created MFs and MDFs but instead use my raw flats and dark flats, selecting Create Masters.

Ok, well that's a nasty error indeed. I would need to see the data for that as well. Would you be able to upload some of the lights and calibration frames just for a quick check? https://upload.astropixelprocessor.com and upload1 for username and password. Please create a directory "neverfox-nullptr".

I'm also getting this error reliably; should I upload data?  The error goes away if I deselect the flats/master flat, so it looks like it has to do with the flats specifically.

That sometimes happens when there's an issue with the data itself, can you check the FITS headers information of your flats to see if the settings are correct (offset etc)? After that I can check your data for sure to reproduce and see if it's a bug or the data.

The FITS settings seem to be fine.  Interestingly, if I create master flats and then use those instead of trying to create the masters from flats, the error does not occur.  It only seems to occur if I load lights, flats, darks, and dark flats and attempt to normalize in one go.

Oh interesting indeed, would be great if you could upload a small subset of those frames and the masters for us to reproduce.

You can if you want, upload some of the relevant subs to our server;

Go to https://upload.astropixelprocessor.com and use upload1 as username and upload1 as password.

Create a directory named “geordan-flatsnullptr” and upload in there. Thank you!

Well that's confusing -- I tried to reproduce the error (to get the exact steps to cause it) and now it won't happen.  Figures.  I'll still upload some files; maybe you'll discover something in them that hints at a failure (or maybe it will fail when you try).

Sorry about that, there was an issue with the new cable for faster internet. It should work now and be faster.

Done; uploaded 3 lights, flats, and dark flats from 2 sessions (disregard the top level Dark and Flat folders).  The lights were shot through a dual Ha/OIII filter, so I would have loaded them using Ha/OIII Extract Ha.
