Issue Push Notification Service Worker Files not being served as "Content-Type: application/javascript"

[Sally1]

Hello,


My site runs the OneSignal web push notifications plugin ans I have some issues with the service worker files not being served as "Content-Type: application/javascript".

OS	‪CentOS Linux 7.7.1908 (Core)‬
Product	Plesk Obsidian Version 18.0.23 Update #4, last updated on Feb 11, 2020 03:41 AM

Apache and Nginx Reverse Proxy.

Additional directives for http and https:

# TTFB
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 100
# Allow Origin
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin *
</IfModule>


Additional Nginx directives:


gzip on;
gzip_disable "MSIE [1-6]\\.(?!.*SV1)";
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_min_length 256;
gzip_types application/javascript application/rss+xml application/vnd.ms-fontobject application/x-font application/x-font-opentype application/x-font-otf application/x-font-truetype application/x-font-ttf application/x-javascript application/xhtml+xml application/xml font/opentype font/otf font/ttf image/svg+xml image/x-icon text/css text/html text/javascript text/plain text/xml;



I would need the following URLs to be served as with this content-type:

yoursite.com/wp-content/plugins/onesignal-free-web-push-notifications/sdk_files/OneSignalSDKWorker.js.php

yoursite.com/wp-content/plugins/onesignal-free-web-push-notifications/sdk_files/OneSignalSDKUpdaterWorker.js.php

How can I fix this?

Thx
Sally
