"exec format error"

I tried to install Deepstack on a Raspberry Po 4B + with 8 Gb Ram using " docker pull deepquestai/deepstack". It did install Deepstack without errors. After that I run the command:
docker run -e VISION-SCENE=True -v localstorage:/datastore -p 80:5000 deepquestai/deepstack and that one stopped with : caused "exec format error"standard_init_linux.go:211: exec user process caused “exec format error”.
Is that due to the wrong architecture or is it something else and can that be solved.
By the way: I use the new RasP IOS 64-bits (to make use of the full 8 Gb RAM). Could that also be a problem?

i think, there is no docker (arm) image for the raspberry pi.

you would have to follow the following instructions

I am waiting for a docker version for raspberry pi
