Error MessageNo valid config found for booking an appointment for catalog id

[Siva Ponnada]

I am working on walk-up experience appointment booking.
Created a record producer for the table wu_appointment with 2 out of the box variable sets
sn_walkup_variable_set and sn_appointment_variable_set
when i am clicking on try it UI action, getting the following error
No valid config found for booking an appointment for catalog id : 408d7923877bd1108c10fcc5dabb35b5
I am facing this issue because of sn_appointment_variable_set. This variable set has a macro sn_appointment_variable_set
which is not displaying on the screen. hence this issue.
Could you please help me resolve this issue.
Thanks in advance!

But the same variable set is working fine in another record producer which has been available OOB (ex: SC Walk-up Appointment)

@Siva Ponnada I just tried in my  PDI , it worked after clicking it on "try it".

Did you copied the record producer, in walkup scope.

i suspect the issue is with the macro "appointmentBooking_SelectMacro"

[RaghavSh]

@Siva Ponnada that is an OOB macro, should not cause issues unless you have any customization there, I just copied the RP and it worked fine.

@RaghavSh I have tried in 3rd instance (now it is on nowlearning instance) 
Copied the RP, still the same issue.

@Siva Ponnada are you copying the RP using copy button and in walkup scope?
