Power Platform Community Forum Thread Details

Hi,

I am building an agent in Copilot Studio that generates
memos. My topic flow is:

1. Adaptive Card collects user inputs (7 text fields)
2. Variables are confirmed populated (verified via debug
message node all values display correctly)
3. Variables are combined into one text variable (AllDetails)
using Power Fx
4. AllDetails is mapped to an AI Builder Prompt input
parameter ({{all_details}})
5. The prompt generates a scope memo

Issue:
The AI Builder Prompt generates output, but it ignores the
input values completely. Instead of using the provided audit
topic, contact name, dates etc., it generates generic
example content (e.g., "Jane Smith", "IT General Controls",
dates from 2024).

This suggests the variable value is either not being passed
to the AI Builder Prompt at runtime, or the prompt is not
receiving it correctly when called from a Copilot Studio
topic.

My questions:
1. Is there a known issue with AI Builder Prompt actions
not receiving mapped variable values from Copilot Studio
topics?
2. Is there a specific way variables should be mapped to
AI Builder Prompt inputs to ensure values are passed
correctly at runtime?
3. Is there an alternative approach to pass topic variables
into an AI Builder Prompt action reliably?

Thank you for your help.
