standardize the error raising in both GraphQL Resolvers and Controllers.
Now, All user aware errors should be throwed with `HttpException`'s variants, for example `NotFoundException`.
> Directly throwing `GraphQLError` are forbidden.
The GraphQL errorFormatter will handle it automatically and set `code`, `status` in error extensions.
At the same time, the frontend `GraphQLError` should be imported from `@affine/graphql`, which introduce a better error extensions type.
----
controller example:
```js
@Get('/docs/${id}')
doc() {
// ...
// imported from '@nestjs/common'
throw new NotFoundException('Doc is not found.');
// ...
}
```
the above will response as:
```
status: 404 Not Found
{
"message": "Doc is not found.",
"statusCode": 404,
"error": "Not Found"
}
```
resolver example:
```js
@Mutation()
invite() {
// ...
throw new PayloadTooLargeException('Workspace seats is full.')
// ...
}
```
the above will response as:
```
status: 200 Ok
{
"data": null,
"errors": [
{
"message": "Workspace seats is full.",
"extensions": {
"code": 404,
"status": "Not Found"
}
}
]
}
```
for frontend GraphQLError user-friend, a helper function introduced:
```js
import { findGraphQLError } from '@affine/graphql'
fetch(query)
.catch(errOrArr => {
const e = findGraphQLError(errOrArr, e => e.extensions.code === 404)
if (e) {
// handle
}
})
```
