Hydra: Failed to up my own docker image

I’m trying to build and up my own hydra docker image. The build process finishes normally, but when I try to up the container, I face the following error:
time="2020-05-04T22:33:36Z" level=fatal msg="Unable to open configuration JSON Schema." error="stat /.schema/config.schema.json: no such file or directory"

To build my image, I’m using the command that is in Dockerfile
GO111MODULE=on GOOS=linux GOARCH=amd64 go build && docker build -t oryd/hydra:v1.0.0-rc.7_oryOS.10 . && rm hydra

And then, I’m following theses instructions to up Postgres and hydra (I’m replacing with my docker image):

During the process, I found no errors, only when I tried to up the container, that this error occurs. My branch is updated with the newest version of master.

Does somebody know why this is happening?

Use (and check) the makefile:

make docker
