API returns text/html code 200 instead of JSON with error
Dear artisans, I'm looking for your experience with Inertia, for a JSON issue I can't fix properly. Here is the problematic page on GitHub (https://github.com/hrsa/calendize/blob/master/resources/js/Pages/Auth/Login.vue).
I do an API call to the controller (https://github.com/hrsa/calendize/blob/master/app/Http/Controllers/UserController.php) to check if user's email exists and it works well - until, in a day or so, it doesn't. Nothing changes in the code, but the response starts coming back as text/html, thus messing up the logic. What's really frustrating is that this behavior is random - the app may run 1,2,3 days - and suddenly goes into "text/html" mode when calling the API. What's more, i've dumped the controller response - and it's JSON, as one expects. So it gets transformed somewhere... but where? The code seems logical and fine, what 🐘 in the room am I missing here?

@gych Thanks for the idea! I actually didn't know about that package, it's definitely worth using.
However, i feel that the problem is elsewhere, because the same "200 text/html instead of what was requested" seems more general with Inertia. I also have the same problem with the login controller, which is supposed to return a 302 redirect (and it does normally), but sometimes it also returns "200 text/html" for no apparent reason. For example, i've rebooted the server and now it works perfectly, but in a day or so it will switch to "200 text/html" again.

Narrowed it down to a potential nginx problem, since the FIRST response is actually returned as "200 text/html". If a request is repeated - the response has correct code. If you have ever had such issues with nginx, i'd be really thankful for your insights!

Finally, the culprit was gzip compression in my nginx config. After having disabled gzip, i get consistent responses with correct codes!

I think i got it right this time! Let me share the process with those who'll read this thread - and maybe it'll help someone sometime.
The culprit wasn't nginx, because the issue came back. I asked for help everywhere i could (with no reaction whatsoever), and started examining the system again.
The server went into text/html mode randomly - sometimes in an hour after deployment, sometimes - in a day or two. But it was never longer than 2 days.
When getting those pesky text/html responses, i noticed the increased response time - it grew from 200-300 ms to 950-1500 ms. That got me thinking - if nothing else is happening on the server, why does it become so slow all of a sudden?
So i ssh'd to the server, and started looking at the load. Memory usage seemed OK, but i noticed that the CPU was loaded at 93%! After 10 minutes, CPU load didn't decrease at all, so i started looking for a reason why the usage was so high - using top to find out that the php container was using all that power and then - using docker top php to see that there were some strange processes /tmp/kinsing and /tmp/kdevtmpfsi running for a long time and using CPU.
Then, with some googling, it wasn't hard to figure out that it was a crypto-miner malware the crept it through the port 9000 which was exposed by mistake. Fortunately, it ONLY invaded the docker container - so a quick rebuild was enough to get rid of it instantly. After properly sanitizing the exposed ports - i saw a multitude of incoming connections trying to start a "debugging" session on my previously exposed 9000 port - so yeah, that finally was the logical answer to this random bug!
The moral of the story is simple - be sure to never expose more ports than needed in your docker configuration and your server! I hope this helps someone who struggles too!
