I use the docker image of CODE (LOOLWSD 2.1.2 (git hash: 4f4593a) LOKit Collabora Office 5.3-15 (git hash: 6a0cbf1)) linked with seafile. In the Calc app I clicked on >Insert >Special character (I use the german version so maybe the naming is different) and got nothing in the browser but the error log: TypeError: this._fontNames.options[this._fontNames.selectedIndex] is undefined bundle.js:16797:7 _onFontNamesChange https://collabora.mydomain/loleaflet/4f4593a/bundle.js:16797:7 fillFontNames https://collabora.mydomain/loleaflet/4f4593a/bundle.js:16708:3 _onSpecialChar https://collabora.mydomain/loleaflet/4f4593a/bundle.js:5882:4 _executeAction https://collabora.mydomain/loleaflet/4f4593a/bundle.js:17648:4 _onItemSelected https://collabora.mydomain/loleaflet/4f4593a/bundle.js:17748:4 dispatch https://collabora.mydomain/loleaflet/4f4593a/bundle.js:48315:16 add/elemData.handle https://collabora.mydomain/loleaflet/4f4593a/bundle.js:48128:6 trigger https://collabora.mydomain/loleaflet/4f4593a/bundle.js:51386:5 triggerHandler https://collabora.mydomain/loleaflet/4f4593a/bundle.js:51460:11 itemClick https://collabora.mydomain/loleaflet/4f4593a/bundle.js:62935:78 proxy https://collabora.mydomain/loleaflet/4f4593a/bundle.js:44076:11 dispatch https://collabora.mydomain/loleaflet/4f4593a/bundle.js:48315:16 add/elemData.handle https://collabora.mydomain/loleaflet/4f4593a/bundle.js:48128:6 Perhaps this bug is related to Bug ID 34882
I'm using the exact same software versions, also in German, but I don't get an error. The feature is working properly.
I tested again today and it turns out that some csp headers were set incorrectly in the nginx configuratino.
