Github actions, self hosted runner Error: unable to verify the first certificate

Question

I am using self hosted runner behind a corporate proxy. I added our certificates but when doing :

  - name: Setup Java
    uses: actions/setup-java@v2
    with:
      distribution: 'adopt'
      java-package: jdk
      java-version: '11'

I am getting the error :

Error: unable to verify the first certificate

Any hint? Thank you

Adding env :

   env:
     - name: SSL_CERT_DIR
       value: "/etc/ssl/certs"

In runner deployment fixed the issue.
