Cannot mark items as dispatched - parcel.royalmail.com

[MrD2018]

When trying to mark items as dispatched, either using the bulk method or individually, nothing happens. This has changed recently. Works in Chrome and Firefox.

Code: Select all

TypeError: Promise.withResolvers is not a function

Can you show the script that's in? I'm not seeing it on the main site. Still, without being able to test, it won't help much.

[MrD2018]

The name of the script is "main.729e01f5133628272b1b.js".

Sorry, I'm going to need the host and path, as well (the ones I tried didn't work).

[MrD2018]

Here is the path -

https://business.parcel.royalmail.com/a ... 0002842858

Thanks. Here's a potential workaround using a Modify HTTP Response filter.

Code: Select all

[["business.parcel.royalmail.com",["/main\\.[0-9a-f]*\\.js/",["/^/","Promise.withResolvers=function(){let resolve,reject,promise;promise=new Promise((res,rej)=>(resolve=res,reject=rej));return{promise,resolve,reject}};"]]]]

If it works, great; if not, it's up to you if want to keep going with the back-and-forth, or give up and just use another browser.

I have tried the filter and it works, thanks. Can you explain to me though what exactly was causing the page not to work and how the filter corrected it? It looks complicated but it would be good to understand how it works.

how the filter corrected it? It looks complicated but it would be good to understand how it works.

Basically the filter polyfills the withResolvers() convenience function that Pale Moon currently doesn't implement.
