Field Value not available in Enhance Copilot to Act on Data with Conversational Language

For this module: 

https://trailhead.salesforce.com/content/learn/projects/connect-data-cloud-to-copilot-and-prompt-builder/enhance-copilot-to-act-on-data-with-conversational-language?trail_id=unlock-your-data-with-data-cloud

All prior modules in the Trail work per instructions and have been completed.

The playground has not expired.

Steps 1-7 work as described.

Step 8 fails - there are no Field values to select in the Filter Records section.

Any ideas? Seems like a skipped step but I've reworked prior modules with no success.

Update: Seeing Errors

• Reservation_1 (Get Records) - Because the sObjectOutputReference field is set, you also need to set the following fields: object.
• Unified_Link_2 (Get Records) - Because the sObjectOutputReference field is set, you also need to set the following fields: object.
