Callback Not Returning Data in Offline Rhel 7.6 Server


My team and I cannot get our Dash application to function on the Rhel server we are using. We narrowed down the issue to one callback that is not returning JSON data, which is then preventing the rest of the callbacks to continue because they are reliant upon the JSON object. The application runs fine on our local windows machines, but as soon as we attempt to run it on the server it gets hung up on the aforementioned callback with no error message posted. Any help is much appreciated.
