Debug bitmap help

I started a little project this evening with the intent of generating QR codes into a 1 bit bitmap. However the bitmap debug has me a bit baffled. Could someone take a quick look at this an tell me what I might be doing wrong? The template data is the bitmap I am trying to display. The bitmap is 24x24, I am using LUT 1 as that was recommended for 1 bit bitmaps, bytes_1bit for the data type and color depth, TRACE is 0 because the image starts at the top left and goes right and then down, LUTCOLOR rgb24?, and WHITE as the color.
I am sure I am doing something stupid. I'm just too ignorant to figure it out.
CON
_xtlfreq = 20_000_000
_clkfreq = 270_000_000
VAR
byte qrbmp[72] ' 24x24 bitmap.
PUB gen() | i
bytefill(@qrbmp,0,576)
' Debug the template
i := 0
debug(`bitmap QRCode SIZE 24 24 DOTSIZE 8 LUT1 bytes_1bit TRACE 0 LUTCOLORS rgb24 WHITE)
repeat 72
debug(`QRCode `uhex_(template[i++]))
DAT

This works, at least to get the pixels displayed... whether it is doing what you want is another matter.
I swear that was my original combination, but it didn't work. Works now!
Now to figure out why it doesn't like my bitmap.
Thank you!
@larryvc Thank you so much! I have it working now perfectly!
