Bug: TypeError on every invoke in Discord

[MaikoTan]

Describe the bug

Every time I enter /nai in Discord with some prompt w/ or w/o negative prompt, it would always returns 发生未知错误. But this never happens with the OneBot adapter.

Steps to reproduce

1. Install the plugin
2. Enter /nai (loli)
3. Got the erreur !

Expected behavior

Parse the input properly and then return the generation back.
