Uploading a file that Realm function can refer to

Hi All,

I have imported node-apn into my Realm project but I have difficulty calling the configuration function because one of the params refers the the path of the token key file:

  var apn = require('apn');
  const apnKeyId = context.values.get("apnKeyId");
  const teamId = context.values.get("teamId");
  const filePath = "mykey.p8";

  var options = {
    token: {
      key: filePath,
      keyId: apnKeyId,
      teamId: teamId
    production: false
  var apnProvider = new apn.Provider(options);

I tried uploading the p8 file using hosting and using URL path to refer to it but it couldn’t be found.

My question has 2 parts:

  1. Where can I upload the file?
  2. How do I reference it?

Thank you so much for your help! Much appreciated.
