My trailhead playground1 -Your quick action doesn’t include the 'Status,' 'Case Owner,' and 'Internal Comments' fields. Make sure you edit the quick action’s layout to include these fields.

Hello Renuka,

As per instruction.

Go to set up -> Object Manager -> Cases -> Buttons Links and Actions

Edit quick action and select Status, Case Owner and Internal Comments fields.
