Invalid PKCS#8 data. - IOException

Hi, I'm trying to configure Firebase Messaging but I'm got the error bellow:

Invalid PKCS#8 data. - IOException (... < NotificatorFirebase:79 < <gener:-1 < *:-1 < ... < NotificatorManager:70 < ...)

I dont know if I put some wrong data, I cant find in the forum useful help.

My config entry:

    <entry key='notificator.firebase.serviceAccount'>
    {
      "type": "service_account",
      "project_id": "safer-app",

There must be some issue with the service account. If there are some special characters, they need to be escaped to make it a valid XML file.
