Browser stops reading javascript chunk if it is too big without any error message

I have encountered a strange problem in my website.

The main steps are that my web app in Flask processes selected data and sends the results to the user and it is then plotted by D3.js. Some extra tables are also shown etc..

If the resulting data is very big (hundreds of MB), then the page is rendered, the tables are there and no error message is given, however the javascript chunk where the big data is used seems to be ignored by the browser. No global variables or plotting.

If the data is of reasonable size, then everything works, the chunk is executed and variables are there.

I tested this with all modern browsers, no error message. I'm just wondering, why this happens.

All the best, L.
