Hi everyone,
I am currently blocked on the Craft an Effective Prompt Template challenge from the Become an Agentblazer Legend 2026 (Service Agent Customization with Prompt Builder) module.
Even though my prompt template is saved, successfully activated, and the "Deactivate" button is visible and enabled, the Trailhead assessment keeps failing with the following error:
"We can’t find the merge field {!$Input:Contact.FirstName} in the prompt template."
I have already verified that Einstein is fully enabled and active in my Org, and I am using the correct special Developer Edition Org requested for this module. I also tried deleting the text and inserting the resource strictly using the "Insert Resource" picker tool (which properly turns into the visual blue token button in the UI).
Has anyone faced this specific validation sync issue or found a workaround regarding the selected LLM model or hidden spaces when Einstein is active? Any guidance would be highly appreciated!
Thank you!
