I am using pants in my ci and seeing the following error. I am using 
docker_environment
to build pex binaries, copy those binaries to docker image (
Dockerfile
has COPY command), build this new image and publish this image to ECR Repository using 
pants publish
command. The build and docker files are in the thread. If anyone has any pointers on why this error might be happening, would love your help.
Copy code

are you using the 
env(..)
construct in the same BUILD file as your 
docker_environment
target? (I think that could be the issue.. thought it was called out in the docs, but seems not)
b
In my 
docker_environment
target, I am not using 
env()
construct, however I am using it inside 
docker_image()
target and in the 
BUILD
file . Both of these are in separate 
BUILD
files. 
docker_environment()
target is in the 
BUILD
file which is in the root directory of monorepo, while 
docker_image()
target is in the 
BUILD
file which is in the project directory e.g. 
monorepo/projects/projectA/BUILD
c
Ok, that should be fine. Something else isn’t, but I’m not sure what..
