What is the function of the triggercontroller?

When I load a product page I see that a call is made to index.php?controller=trigger&ts=1677152722

What is returned is {"status":"failed","error":"Forbidden"}

When I look into the source code I see something about a scheduler but that doesn't make things much clearer. The line "ServiceLocator::getInstance()->getScheduler();" gives me nightmares about Symfony style complexity.

It's a synthetic event to trigger scheduler. To run scheduled and deferred tasks. 

In ideal deployment, this would not be needed, because scheduler events would be triggered by cron or external process. That's not realistic for small shops, so it's emulated using this synthetic events.

Tell me you have never wrote a test without telling me you have never wrote a test.

But what does that "failed"/"forbidden" reaction that I see mean for the functioning of my webshop?

What tb version are you using? In 1.3, this issue was caused by CORS preflight requests.

Not a critical issue, because trigger was executed during preflight request. Fixed anyway.

[musicmaster]

Yes, this is 1.3.

Let's blame it on CORS then 🙂

If you are unable to update to 1.4, you can applie these lines (warning PHP7 syntax used - I know you are working on some PHP5.6 servers, for some reason)
