I am trying to use LoadStrings() in a p5.js and in the console, I get the error “p5.js:60518 Fetch API cannot load file:[FILENAME].txt. URL scheme must be “http” or “https” for CORS request.”
I googled it and people said that it only works on firefox but it doesn’t even work on firefox for me
here is the code in question:
var track = [];
function setup() {
loadStrings(“track.txt”, getText)
}
function getText(data) {
track = data;
}

Because of that, now we may need an http server to serve the sketch's \`index.html\`

do you have any suggestions for how i can fix this
id rather not have to host a local server backause im actually working on a commision and it would be a bit of bother to have to get them to host a locl server aswell and set the file up.

Anything relying w/ the new Fetch API doesn’t work w/ that Chrome workaround.
Fetch API is compatible w/ the `file://` scheme on Firefox though.

As the name of the site implies: [Chrome-allow-file-access-from-file.com](http://Chrome-allow-file-access-from-file.com)
That workaround is for Chrome-based browsers only.
For Firefox-based 1s you just use the trick described on the 1st link I’ve posted:
> **[Reason: CORS request not HTTP](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSRequestNotHttp#Local_File_Security_in_Firefox_68)**
>
> CORS requests may only use the HTTPS URL scheme, but the URL specified by the request is of a different type. This often occurs if the URL specifies a local file, using a file:/// URL.
