Stuck at Explore Data with Agentforce Grid badge

Hey All , I have been stuuck at clearing this badge where we create JSON summary from the Account summary prompt builder in  Agentforce Grid - I Created a new playground as mentioned in the instructions.  

I used 

{{ ref('Account','Id') }}

but not able to generate the JSON code - its been a while ( around 30 minutes ) , tried refreshing multiple times . Anyone tried this recently ?
