Here is the same issue in text form. Line numbers have slightly changed:

I tried to work around this problem by surrounding the calls on readFileSync with a ternary operator that checks if the file exists (using existsSync) and in the 'else' part returns null. This works if applied to the case of ../keys.pub and ../keys in src/auth/constants.ts. Example:

privateKey: existsSync('../keys') ? readFileSync('../keys') : null

Once that is fixed, a similar problem occurs in src/amp/amp.controlers.ts for file ../black-list.txt. This can be fixed in a similar manner. Again, a ternary operator when variable isValid is initialized, setting it to true if no blacklist file was loaded.
Then, same problem in src/app.modules.ts where a 'database config' file ../monitor_db.json is loaded. Although the missing file can be worked around again by using the ternary operators here was well, running the code now stops due to missing information about which database to use:
