the image file could not be accessed error on google chrome page reload

[Izaanaami]

hi. first of all thank you for your amazing project.
I have a problem that seems very odd to me and have been stuck on it for past few days. when I load the pannellum on google-chrome, the first load works completely fine, but when I refresh the page, I get the error that says image file could not be accessed. I have tested it on other browsers and even other computers and even on VM with the same chrome version, they all work without a problem. I even reinstalled my chrome.

I am using your project on nextjs if that's relevant. and here are the console errors and image file headers:

console error:
GET http://localhost:3000/panorama/allSites.jpeg net::ERR_FAILED 200 (OK)

response headers:
accept-ranges: bytes
cache-control: public, max-age=0
connection: keep-alive
content-length: 10530381
content-type: image/jpeg
date: Sat, 28 Dec 2024 08:26:19 GMT
etag: W/"a0ae4d-193e9d85c11"
keep-alive: timeout=5

I have even tried to serve the image from nginx, and have tried serving it using an api from nextjs. I have tried using the pannellum from an iframe, and I have tried using it by editing the js file so that I can import it into my code without it calling itself on the window object.

and one more thing I am concerned about is that, does the library work in the future updates of the browsers, maybe in 5 to 10 years from now? do you have any plan to update the library if any breaking changes happens?

Pannellum just uses a standard XMLHttpRequest, so it's a configuration issue on your end. My guess is that it's a CORS issue. I'd recommend looking at the responses to this Stack Overflow question: https://stackoverflow.com/questions/22665232/what-can-cause-chrome-to-give-an-neterr-failed-on-cached-content-against-a-ser

I can't predict the future, but browser developers generally don't like breaking commonly-used web platform features such as WebGL, so that answer is probably "yes."

Builds aren't included in the Git repository (note the lack of a build directory), so pointing a CDN at master / the Git repository isn't going to work. If you want to use a CDN, look at the downloads page, which shows you how to use the latest release via NPM / jsDelivr.
