breeze initial run fails on raspberry pi

my configuration

pi@raspberrypi:~/code/airflow $ uname -a

after just running ./breeze the first time, the images seem to download ok, but the following error occurs. Trying again always runs into the same error.

Step 109/133 : RUN if command -v airflow; then         register-python-argcomplete airflow >> ~/.bashrc ;     fi
 ---> Running in 38c00df94802
standard_init_linux.go:211: exec user process caused "exec format error"
The command '/bin/bash -o pipefail -e -u -x -c if command -v airflow; then         register-python-argcomplete airflow >> ~/.bashrc ;     fi' returned a non-zero code: 1

on my host system register-python-argcomplete is there and seems to be functional. I am guessing this is not being called in the context of my host system but I am not so sure about that. Any advice on what I am doing wrong here?

Raspberry PI is an ARM-based computer not x86 so there are likely some problems with the architecture of the argcomplete (looks like from the error at least) - looks like x86 binaries used on ARM.

I know there were some successes with running Airflow on Raspberry PI by @TobKed so maybe he can have some insights.

thanks for the reply.

if I run the shell command myself it works btw. not sure what about it looks like x86 binaries are in play unless it's that 'exec format error'
