I cannot get App-Level Env Vars to be passed to my spring boot app

Hi,

I am struggling to use app-vars :)

Here is my list of env vars:

REGION = ams3
BRANCH_NAME = dev
ACTIVE_PROFILE = dev
DO_SPACES_SECRET = MY_SPACES_SECRETS
DO_DB_PASSWORD = MY_DB_PASSWORD

Here is my config and properties files:

app.yaml:

name: project_1-admin
region: REGION
services:
  - dockerfile_path: Dockerfile
    github:
      branch: BRANCH_NAME
      deploy_on_push: true
      repo: project_1/project_1
    name: web

Dockerfile:

FROM gradle:7.5-jdk17-alpine AS _build
COPY --chown=gradle:gradle . /home/gradle/src
WORKDIR /home/gradle/src
ARG ACTIVE_PROFILE
ARG DO_SPACES_SECRET
ARG DO_DB_PASSWORD
RUN gradle web:build --no-daemon --debug

FROM openjdk:17-jdk-slim
EXPOSE 8080
RUN mkdir /project_1
COPY --from=_build_ /home/gradle/src/web/build/libs/web*SNAPSHOT.jar /project_1/web.jar
ARG ACTIVE_PROFILE
ARG DO_SPACES_SECRET
ARG DO_DB_PASSWORD
ENTRYPOINT ["java", "-jar", "/project_1/web.jar"]

application.properties:

spring.profiles.active=${ACTIVE_PROFILE}

application-dev.properties:

digital.ocean.spaces.secret=${DO_SPACES_SECRET}
spring.datasource.password=${DO_DB_PASSWORD}
