Getting this error and am not sure what the problem is. The log shows the image plate solved successfully, the script then downloads Vizier data from UCAC3 catalog, showing 3070 objects inside the image and 12,520 catalog stars, but then get the error:
*** Error: Failure to process image file 'F:/Temp/Image_300.000secs_00000520.fit': TypeError: posPx is null.
