It looks like the "data =" field was not what mkimage wanted it to be.
Unfortunately, the extent of documentation on this is:
"data : Path to the external file which contains this node's binary data."
Which is not helpful given that the format is peculiar.
The following are examples I found while searching:
data = /incbin/("${2}");
data = /incbin/("./vmlinux.bin.gz");
data = /incbin/("path/to/data/file.bin")
data = /incbin/(\"${KERNEL}\");
I am guessing the first portion is a path and the second is the file
name relative to that path. Why that format is needed is unexplained.
I don't have anything good to say about u-boot/denx documentation.

Sorry, I forgot to include this stdout from running mkimage manually:

Note the "Data Size: " fields being wrong. The real Image 0 file is
200KB and Image 1 is 5.7MB.

Hello
I am trying to get LEDE to build for a new device, and my device
needs a FIT image.
However, mkimage appears to be putting out a FIT file without the
actual data files being included. All the rest of the FIT file
formatting looks right on cursory inspection, but the data files
which were to be included are missing.
Any ideas?
My .its looks like this:
/dts-v1/;
/ {
description = "LEDE FIT image for TEW827DRU";
#address-cells = <1>;
images {
script@0 {
data =
"/home/user/proj/lede/newrouter-ledeproj-try6/target/linux/ipq806x/image/flash-tew827dru.scr";
description = "u-boot-HTTP firmware update script";
type = "script";
compression = "none";
arch = "arm";
hash@0 {
algo = "crc32";
};
};
ubi-image@1 {
data =
"/home/user/proj/lede/newrouter-ledeproj-try6/build_dir/target-arm_cortex-a15+neon-vfpv4_musl-1.1.15_eabi/linux-ipq806x/tmp/lede-ipq806x-TEW827DRU-squashfs-factory.bin";

};
};
