Error on Mobile Client: Can not read property firstChild of null

Bobblue · October 22, 2024, 7:51pm

We have since around 3 days a persistent issue in one of our private channels.

I already tried to delete all messages in there via the API. This solves the issue temporary but when new messages appear the issue comes back. Also I cleared the app cache and tried logout and new login.

App Version: 2.21.0 (Build 565)
Server Version: 10.1.1 (Build 11162711545
Datenbank: postgres
Version des Datenbankschemas: 127

Issue is there just on Mobile Clients but on Android and iOS for multiple users

Hi Bobblue, thank you for reaching out, and I’m sorry to hear you’re still experiencing frustration with this. It might help to review our Mobile Troubleshooting Guide for additional tips, and I also recommend checking if the channel bookmarks feature is causing the issue as the logs suggest errors there. Let us know how it goes!

Bobblue · October 30, 2024, 7:23am

Hi John
I have no clue where I could adjust a bookmark feature. Can you help me here.
I tried to minimize the markdown nodes rendering on mobile devices. And deactivated the inline rendering. Both with no effect. I’m willing to change (try and error) my configurations but as all worked fine for years it must have something todo with server updates to 10.x or App update from my opinion
