# “Nothing Available” When Mapping Outputs

**Symptom:**\
When mapping fields in a follow-up action, the Output dropdown shows “Nothing available.”

**Reason:**\
The Outputs were not re-added after the last test or the Custom Action was saved before the fields were mapped.

**Solution:**\
Edit the Custom Action, click **Run Test Request**, open **Show Full Response**, and re-add the Outputs. Save the action before returning to the screen editor. Then reopen the mapping menu, and the Outputs should appear.
