When using Prompt Flow, you notice that your flow is failing at the 'aggregate' node. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The input data from the previous node does not match the expected schema of the aggregate node.
The aggregate node expects a specific schema and iteration results from the previous node; if these are missing or mismatched, the flow fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The input data from the previous node does not match the expected schema of the aggregate node.
Why this is correct
Prompt flow nodes require strict input/output alignment.
- ✗
The system prompt is too long.
Why it's wrong here
System prompt length does not affect node logic.
- ✗
The search index is empty.
Why it's wrong here
This would affect the search node, not the aggregation node.
- ✗
The model is too busy.
Why it's wrong here
This would cause a latency error, not a node-specific failure.
