Bookmarklet fails on Twitter links

Pasting the link to the textbar of youtube-dl-server works. But when using the bookmarklet it fails.

I'm using the bookmarklet link provided from webinterface:

javascript:fetch("https://FQDN.OF.MY.SERVER/api/downloads",{body:new%20URLSearchParams({url:window.location.href}),method:"POST"});

Many other sites (eg. Youtube) works. I'm using Safari, but doesn't matter. It's the same behavior with Firefox.

Looks like a problem with CSP. To avoid this, I've created a shortcut for Safari and do the same like your curl example:

curl -X POST --data-urlencode "url={{url}}" http://{{host}}:8080/api/downloads

This is my shortcut, works in iOS, iPadOS and macOS:
