Fiddler modifying https json file (app.map) on it's own

I was trying to debug webpack generated application and webpack generates big JSON file called app.map. I was getting this error:

Source map error: SyntaxError: JSON.parse: bad control character in string literal at line 1 column 790260 of the JSON data
Resource URL: https://test.sceal.dev/js/app.bundle.js
Source Map URL: app.map[Learn More]

I was trying everything and nothing worked until I found out that if I disable fiddler and add test.sceal.dev in hosts it works. So JSON file is somehow modified by fiddler which makes it unusable. It should never actually modify the request unless I tell it to.

Am I missing something simple or is this really a bug?

    It's caching issue I guess, probably not a bug, closing the ticket.

    I cleaned the cache and enabled fiddler and issue reappeared.

    It might be fiddler caching issue or something like that too as now after it worked with hosts, I commented out hosts and re-enabled fiddler and it started working. Not sure what happened.
