File Versions not visible on web interface

[johannes314]

Expected behaviour

I am expecting to see file versions on the webinterface but I don't
I already discussed it briefly at the nextcloud forum:
https://help.nextcloud.com/t/file-versioning-enabled-but-not-working/21146/5

Actual behaviour

The file versions are created and I can find them in the file explorer but in the web interface there is no version history. There is just empty space.

Anything in your browsers console (F12) or your nextcloud.log file?

Hi @MorrisJobke and @nickvergessen
unfortunately i ran into the same issue with Nextclud 15.0.2.

Versions are stored in users files_version directory properly

but neither appear in the browser nor appear e.g. in collabora (i.e. gewicht.xlsx).

Nothing was written to the nextcloud.log.

Debian Stretch 9.6 64Bit
Nextcloud 15.0.2
NGINX 1.15.8 TLS 1.3
PHP 7.3
MariaDB 10.3
Redis

files_versions: 1.8.0

In the browser console i received:

TypeError: this.sync is not a function[Weitere Informationen] core.js:2101:14

while selecting the versions in firefox 64.0.2 (64Bit).

Using Edge the console throws:
