LLM node completes instantly, but no return value / empty return value

Using Dify’s official cloud environment.
It’s triggered very frequently; I encounter this problem when using both the qwen plugin and the open router plugin.

Similar problem. Been happening for over 12 hours now.

Hey mate, are you also in a cloud environment? I’m wondering if it’s a Dify server issue.

I’m also experiencing the same issue. Reports that seem to be due to the same cause have also been made on Discord.
