Describe the question
I'm encountering a 500 Internal Server Error when trying to create a select/dropdown field via the Forms API endpoint. The error occurs at:

POST /people/v2/forms/{form_id}/fields

when attempting to create a field with field_type: "select" or "dropdown".

What have you tried that worked?

• Successfully created a form via the API
• Successfully created other field types (date and text) within the form
• Verified authentication is working correctly via other endpoints
• Confirmed proper form_id is being used

What have you tried that didn't work?

1. Basic select field creation:

{
    "data": {
        "type": "FormField",
        "attributes": {
            "label": "Care Category Type",
            "description": "Types of care requests",
            "required": true,
            "field_type": "select/dropdown",
            "sequence": 3
        }
    }
}

2. Adding settings to the field:

{
    "data": {
        "type": "FormField",
        "attributes": {
            "label": "Care Category Type",
            "description": "Types of care requests",
            "required": true,
            "field_type": "select/dropdown",
            "sequence": 3,
            "settings": {
                "multiple": false,
                "allow_other": false
            }
        }
    }
}

All attempts result in a 500 Internal Server Error before even attempting to add options to the field.

Additional context
The error response:

{
    "errors": [{
        "status": "500",
        "title": "Internal Server Error",
        "detail": "An internal server error occurred on our end and we've been notified. Please contact support if the issue persists."
    }]
}
