Having issues exporting AWS SSM parameter value to Nuxt environment variable

Describe the bug

Deployment to production is successful, but I'm having some issues passing a parameter value from AWS SSM to a env file, it's undefined no matter what I do. Thus, my useAsyncData is returning an error.

Here are my codes for the amplify.yml file as well as the runtimeConfig object on my nuxt.config.ts file. Only config.githubSecret is undefined, the public githubBaseUrl is working.

Is AWS SSM not supported for deploying to production? Must I set the environment variables under the build settings on the AWS Amplify console?

Thanks in advance.

amplify.yml

version: 1
frontend:
  phases:
    preBuild:
      commands:
        - nvm install 21.5.0 && node --version
        - corepack enable pnpm
        - pnpm install --frozen-lockfile
    build:
      commands:
        - export NUXT_GITHUB_SECRET=$(aws ssm get-parameter --name "/amplify/d2zk1p9qtbvjcd/main/AMPLIFY_secrets_nuxt_GITHUB_SECRET" --with-decryption --query Parameter.Value --output text)
        - echo "NUXT_GITHUB_SECRET=$NUXT_GITHUB_SECRET" >> .env
        - pnpm run build
  artifacts:
    baseDirectory: .amplify-hosting
    files:
      - "**/*"
  cache:
    paths:
      - node_modules/**/*

nuxt.config.ts

nitro: { preset: "aws-amplify" },
runtimeConfig: {
    /// Tried with githubSecret: "", not working as well
    githubSecret: process.env.NUXT_GITHUB_SECRET,
    public: {
      githubBaseUrl: "https://api.github.com",
    },
  },
