# Appointment Context Required

> An appointment context is required for this fee calculation

## Cause

When calculating fees for appointment-related transactions, an appointment ID must be provided as context.

## Fix

Include the `appointment` parameter with a valid appointment ID when the fee type is `appointment`, then call the same operation again.

## Retry safety

Not retryable until the underlying state or request changes.

## Raised by

No current operation documents this problem type in the OpenAPI definition. If you receive it in production, treat that as a contract gap and tell us.

## Example

```json theme={null}
{
  "type": "https://docs.guile.app/problems/appointmentContextRequired",
  "title": "Appointment Context Required",
  "status": 422,
  "detail": "When calculating fees for appointment-related transactions, an appointment ID must be provided as context."
