express fileupload fails on large file size - html

Question

Please bear with me I'm new to fileUpload express. I have simple form to upload file. It works for file size of around 50MB but it fails for file sizes more than 100MB.
Here is the HTML file:
<form action="/parse"
method="post"
ref="parse"
encType="multipart/form-data">
<input type="file" class="btn btn-secondary input-file" name="inputFile" id="inputFile"/>
<input type="submit" class="btn btn-primary submit-btn" value="Upload"/>
</form>
And here is my initialization:
const fileUpload = require('express-fileupload');
var app = express();
app.use(fileUpload({
limits: {
fileSize: 1024 * 1024 * 1024 * 1024,
abortOnLimit: false
}
}));
It won't even hit my /parse url, it gives the following error on express app console:

Answer 1

No code change is needed. In your package json for start script, have this command:
"start": "node --max-old-space-size=4096 ./bin/www"
Or if you run your node file from command line, run it like:
node --max-old-space-size=4096 PATH/TO/YOUR/EXECUTABLE/NODE/FILE
