Apps using .mjs files (Polls) show a blank page

[HansCronau]

NextCloudPi version v1.54.2 Nextcloud version 27.0.0.8 Polls version 7.1.3

After upgrading my Nextcloud to version 27 and the Polls app to 7.1.3, the Polls app now shows a blank page. It seems I am not the only one, as an issue was filed with the Polls app. It appears all apps using .mjs files (not many) are affected. Inspecting the network tab in my browser, I can indeed confirm that the file polls-main.mjs?v=3d18ca96-5 does not load, instead returning a 404. The Polls issue was closed after a solution was found outside of Polls. Because this solution involved changing Nginx configuration, I believe that, for NCP instances, this should be fixed at the NCP level.
