Cannot create calendar meeting using scheduler api

I am getting the following error when I submit an API call using curl:

I am using using this documenation - I am using the following documenation: Accounts Dashboard | HubSpot

I am getting the following error:

{“status”:“error”,“message”:“formFields contains invalid name(s)”,“correlationId”:“67f90eaa-0000-0000-0b8a-fbaff6cd137e”,“context”:{“formFields”:[“[ExternalBookingFormField{name=phone, value=3472327411}, ExternalBookingFormField{name=date_of_birth, value=447656400}, ExternalBookingFormField{name=all_appointment_type, value=33}]”]},“category”:“VALIDATION_ERROR”}

If I remove the follwoing, then it works.

{
“name”: “all_appointment_type”,
“value”: “33”
}

This is how the form looks like - Screenshot by Lightshot

This is the property “all_appointment_type” - https://prnt.sc/nIghMqFd5qg_

Here you mismatch the property name.

In this picture its show:

In your property label its shows:

So there must be a property Appointment type. If you use the correct internal name then it will be work fine.
