Cannot debayer image due to missing CFA pattern

[knro]

Using PI v01.08.06.1457 and when trying to debayer an image captured with INDI, it complains about missing CFA keyword. However, as you can see in the screenshot, there is BAYERPAT keyword already set in the FITS header (RGGB). So what's going on there? is it expecting a different keyword?

The FITS file is also attached.

I tried it with your attached file and it works without any problems (see screenshot).
I am using version PixInsight Core 01.08.06.1475 Ripley (x64) with all provided updates:

I just checked again and all updated are applied. I am using this on Linux.
