# Cancel Task

A task creator should have the option to cancel a task as long as he **has not accepted the developer's estimation**. 

### Input parameters

* TaskID

### How to call from app

```
import { httpsCallable } from 'firebase/functions';

await httpsCallable(functions, 'cancelTask')({ taskId })
```

### Logic

1. Move the task back to drafts (We should maybe build a function for this so we don't have redundant logic)
2. Remove developer from project members (projects/members) array if no other task with same projectId found
3. We should send an email to the developer if There is someone assigned-
4. Send First Email:
   * to\_email\_adress = email\_of\_assigned\_person
   * template\_name = "tasks-canceled-by-creator->developer"
   * data = {taskData: taskData, taskId: taskId}
