This not an error in PyMuPDF: PNG images only support gray scale or RGB - not e.g. CMYK.
Without at the specific details:
So, any Pixmap not conforming to the above must be converted first.

Sorry, I didn’t found the link can’t be download. This is the file I uploaded.

I suspect it’s a issue in pymupdf for I found similar error in discussion of pymupdf, according to google.

No, definitely not.
The PNG image format itself does not support all color spaces! No PDF tool, including PyMuPDF, can do anything here.

I hope there would be an option to skip the error (e.g. ignoring the image) so that the code can run further.

Again: this is not an error in PyMuPDF!
It is this package's obligation to properly react to images that cannot be converted to PNG directly.
