Fuji X-T3 with FITS image transfer - flips to FITS GGGG Bayer Filter setting

With Kstars 3.5.2 (downloaded today, Build: 2021-02-28T17:27:50Z)

In attempting to save a step in preprocessing I experimented with setting Ekos for FITS image transfers rather than RAW. It appeared to work but on examining the resulting images I find they all have a Bayer filter setting of GGGG rather than the RGGB I set in the Indi Control Panel "Image Info" tab. I get a pop-up window indicating a Debayer error of "Unsupported bayer pattern GGGG".  Upon Debayering in PixInsight I get three channels - all grey, no colour.

Resetting Indi Control Panel back to RGGB does nothing. As soon as the image is taken, the setting (in the left pane) changes back to GGGG.

Any suggestions as to why this is happening?

Quick Aside:  I just went back to Kstars 3.5.0 and tried the same thing - transferring file as FITS.  First image worked, resulted in properly Debayered RGB image. I notice the Indi CP setting was for 8 Bits per pixel.  I changed it to 14 (my camera's value) and the next capture resulted in a grey image with Bayer Pattern of "GBRR" rather than GGGG like 3.5.2 or the correct RGGB setting.  Even stopping the program and power cycling the camera would NOT get me back to a "correct" FITS image with colour.

Here is he FITS header for the one image that did come through (Kstars 3.5.0) with proper RGGB Bayer filter pattern. (note 8 bits/pixel & 3 data axes vs. 16 bit/pixel & 2 data axes with GGGG pattern)

Hey Dave, have you been able to solve the issue? I'm facing the same thing with my new X-T4. I get the error "Unsupported bayer matrix GGGG". Is it an issue with EKOS?

Hi Riccardo, I have not been able to solve this yet. I'm not sure where the issue is... Ekos, Indi, gphoto or...?

I literally just had an idea but I've yet to try it. (I've been composing my response to your question in the Fuji thread...)

I will be sure to update if I have any sort of success.

Riccardo, I had a chance to try the FITS save again...same results as last time.  It just transfers GGGG files that are grey only. I tried a few different configurations (FITS options, Capture module options, Indi Fuji_ccd settings) and always ended up with either a failure or a grey FITS file.  Saving the images took quite a while, on the order of two minutes (conversion from RAW time, I guess)  Way too slow to be useful.  I shoot with the Fuji set to save compressed RAF files (~26MB) to save space as my processing program will successfully handle the compressed files.
I will stick with using RAF files for now.
