When I used a mobile device to use my openwebui and conduct a conversation, the following error was prompted in the reply: Invalid regular expression: invalid group specifier name (the reply from AI can usually return a few words and truncate normally)

I have confirmed that this problem will occur when using all channel source models through the mobile terminal.
I have confirmed that this problem will not occur on the PC side.
There is no error in the console, and all return 200.

Deployment device: huggingface (from the official template) and ubuntu 20
Used device: iOS iPadOS
