1. Is this request related to a challenge you're experiencing? Tell me about your story.

When I use question-classifier node, sometimes I will get timeout errors due to high demand of provider traffics. For now I cannot handle these kind of errors because we do not have error handling fallbacks for built-in nodes (except LLM nodes). So maybe we could add this feature.

2. Additional context or comments
