Details - I use the  Image Builder to build image for my NETGEAR R8000.
Firstly, I tried to build with the command which I had use many times in 19.07.03.But I got error message like this:
WARNING: maxlen exceeds default maximum!  Beware of overwriting nvram!
os-image partition too big (more than 2097152 bytes): Success
make[3]: *** [Makefile:456: /media/nautilus/Data/Personal/Router/openwrt/21.02-RC2/openwrt-imagebuilder-21.02.0-rc2-bcm53xx-generic.Linux-x86_64/build_dir/target-arm_cortex-a9_musl_eabi/linux-bcm53xx_generic/tmp/openwrt-21.02.0-rc2-bcm53xx-generic-tplink_archer-c5-v2-squashfs.bin] Error 1
make[2]: *** [Makefile:186: build_image] Error 2
make[1]: *** [Makefile:124: _call_image] Error 2
make: *** [Makefile:240: image] Error 2
Then, I use the default command like this:
make image PROFILE=netgear_r8000
But I got the same error message.
I can't get any useful message from the error message. And I can build  image  successfully with v19.07.03. That means the envirment is well.
