How do i solve this problem. I am working in small project for which the network camera + audio is very important and URGENT.

Are you sure that you are running the command from the right directory? Can you paste the output of ls?

here is the output of ls command:

app Dockerfile.template

I am using ubuntu 18.04 and have installed balena cli from this page.
I have cloned this package for networking camera. what i did after cloning this repository:
cd balena-cam/balena-cam
balena login ( webauthorizatio login + authorized the balena cli client )
balena push myPI ( app name )
and i got above error.

You should run balena push at cd balena-cam/, the one that has the docker-compose.yml file and it should be fine

I trried to run it from balena-cam/ root folder also wheere this files are showing when i run ls command:

balena-cam docker-compose.yml README.md VERSION
CHANGELOG.md LICENSE repo.yml

But still i’m getting the same errors.
I’m using : ubuntu 18.04, pi 4B 4 gb ram. when creating application i selected the pi 4 os in the dropdownlist .

Hi,

The rpi4 baseimages were added after the release of balena-cam, so this debian snapshot doesn’t exist for the rpi 4. We are looking into updating the balena-cam project, but in the meantime you can create an rpi 3 app and it should work with the current version of balena-cam even on an rpi 4.

ok. thanks i’ll try.
