Short description of error
Strictly speaking, this might not be a bug, but merely unexpected behaviour.
When applying "Convert to => Grease Pencil from Curve" on a bezier curve object, the conversion process disregards parts of the curve generated by "Cyclic U" if the option is checked in the curve's "Object Data Properties => Active Spline" menu. This leads to parts of the curve missing in the generated grease pencil object:

Cannot reproduce on my end tbh.

Just to make sure: could you share your .blend file just before converting?
Here's a file. To make sure, I duplicated the curve and tried converting it, and it behaved as described in the original post. You can see the result as the GP object in the file.
Also, just in case: another unrelated bug I have is caused by my system being too old for current Blender standards. Although it would be odd for that to be the cause here as well, it's something to keep in mind. (Maybe?)

Changed status from 'Needs User Info' to: 'Confirmed'
The error is when the curve has only 2 points. I will take a look.
