Push Notifications: Development not working

Description:

When developing an own whitelabeled App and trying to activate push notifications via APN in development mode not working.

Using a production iOS-App with a production APN device token (for example TestFlight) works fine!

Steps to reproduce:

1. generate APN (production and development) Certificates and copy to the APN formula in settings
2. disable production mode
3. on restart: there is an error certificate does not support configured environment, production: true and APN isn't initialized

I tried to console.log the certificate and the environment informations in /app/bundle/programs/server/npm/node_modules/apn/lib/credentials/certificate/validate.js:

environment = { sandbox: true, production: false }
credentials = { [...], production: true }

so the credentials.production is always true, independant of the switch.

Instead setting the EndpointAddress.production in /app/bundle/programs/server/npm/node_modules/apn/lib/config.js manually to api.development.push.apple.com works.

Expected behavior:

Setting correctly to APN development mode when disabling production.

Actual behavior:

APN development not set correctly

Server Setup Information:

• Version of Rocket.Chat Server: 6.4.4
• Operating System: debian
• Deployment Method: docker
• Number of Running Instances: 1
• DB Replicaset Oplog: enabled
• NodeJS Version: 14.21.3
• MongoDB Version: 5.0.22

Start by reproducing the failure with production mode disabled, then inspect the APN integration and the referenced files /app/bundle/programs/server/npm/node_modules/apn/lib/credentials/certificate/validate.js and apn/lib/config.js. Compare the configured environment with the certificate values; done means development APN initialization succeeds without the certificate-environment error and production mode still works.
