ParsePy: Where To Get Rest API Key In Bitnami Parse Image - amazon-web-services

Question

I am currently trying to connect to my instance of parse-server, created from Bitnami's AWS Parse server image, with the ParsePy python package.
However, the package's register() function requires a 'rest_key' parameter, which I believe to be the parse server instance's Rest API key.
I looked for the key in the following file, which came with the image:
/home/bitnami/apps/parse/htdocs/server.js
And only found parameters labelled masterKey and fileKey. I found a similar question here, but those answers don't direct me to where I would find the key in a Bitnami parse-server image.
Any guidance would be helpful. Thanks!
Edit: The relevant portions of server.js are shared below:
var express = require('express');
var ParseServer = require('parse-server').ParseServer;
var app = express();
var api = new ParseServer({
databaseURI: "mongodb://root:WcbKujWVdiX2#127.0.0.1:27017/bitnami_parse",
cloud: "./node_modules/parse-server/lib/cloud-code/Parse.Cloud.js",
appId: "APP_ID",
masterKey: "MASTER_KEY",
fileKey: "FILE_KEY",
serverURL: "http://34.242.164.250:80/parse"
});
I tried adding a parameter for a restAPIKey before serverURL as follows:
restAPIKey: "REST_API_KEY"
But that simply leads to this error message:
