I have angular 7 site - which I have converted into server side rendering (referring mainly https://blog.angular-university.io/angular-universal/).
I am running site on AWS using 'foreever'. I aways see below error inside my foreever error log file:
(node:23488) [DEP0005] DeprecationWarning: Buffer() is deprecated due to
security and usability issues. Please use the Buffer.alloc(),
Buffer.allocUnsafe(), or Buffer.from() methods instead.
I have not used any kind of buffer in my code, so my guess is it might be coming from node modules I am using. From above log message I am unable to detect which module is having problem.
My current package.json looks like below:
"dependencies": {
"@angular/animations": "^7.0.0",
"@angular/common": "^7.0.0",
"@angular/compiler": "^7.0.0",
"@angular/core": "^7.0.0",

"webpack": "^4.28.3",
"webpack-cli": "^3.1.2",
"webpack-dev-server": "^3.1.14",
"zone.js": "~0.8.26"
}
Is there any way to get more logs ? Can I neglect this error message for now?
Thanks in advance.
EDIT- My package.json has following:
"build-both": "ng build --prod --output-path=dist/browser && ng run
ecokrypt-uiapp:server --configuration=publiclocal
--output-path=dist/server",
"webpack-server": "webpack --config webpack.server.config.js
--ouput dist/server.js --progress --colors",
"build-and-pack": "npm run build-both && npm run webpack-server",
When I build the application (npm run build-and-pack): I see following in my console: I see 2 warnings related to some System.Import()
