# Introduction
Following https://github.com/twentyhq/twenty/pull/13420
What has been done:
- `CreateFieldInput` transpilation to `FlatFieldMetadata`
- `FlatFieldMetadata` validator service
- A lof of transpilation utils from `input` to `flatObject` or
`flatField`
- Created dedicated v2 api metadata services
- Introducing `inferDeletionFromMissingObjectFieldIndex` in the builder,
to avoid diffing every object and field of the current workspace we
allow only generating create/update migration operations, usefull when
passing by the api metadata
## We still need to in another PR:
- Implement a strong unit test coverage and critical functions and
services
- Finalize flat field metadata validation exception for `options`
`defaultValue` `settings` and `relations`
- Finalize `flatObjectMetadata` validation and v2 service refactor
- Plug the new service when feature flag is enabled
In the BE we throw custom errors with precise error codes (e.g.
"LABEL_ALREADY_EXISTS") before catching them in filters and rethrowing
BaseGraphQLErrors (standard errors such as NotFoundError, UserInputError
etc.).
In the FE we were grouping sentries based on the error codes but we were
actually grouping by very broad codes such as "NOT_FOUND" or
"BAD_USER_INPUT", extracted from the BaseGraphQLErrors.
To fix that, we update the BaseGraphQLError constructor api to allow to
pass on the CustomError directly and retrieve from it the original code
and store it in existing property `subCode` that we will use in the FE
to send errors to sentry.
This new api also eases usage of `userFriendlyMessage` that is passed on
to the api response and therefore to the FE when CustomError is passed
on directly to the BaseGraphQLError constructor.
Currently, when a server query or mutation from the front-end fails, the
error message defined server-side is displayed in a snackbar in the
front-end.
These error messages usually contain technical details that don't belong
to the user interface, such as "ObjectMetadataCollection not found" or
"invalid ENUM value for ...".
**BE**
In addition to the original error message that is still needed (for the
request response, debugging, sentry monitoring etc.), we add a
`displayedErrorMessage` that will be used in the snackbars. It's only
relevant to add it for the messages that will reach the FE (ie. not in
jobs or in rest api for instance) and if it can help the user sort out /
fix things (ie. we do add displayedErrorMessage for "Cannot create
multiple draft versions for the same workflow" or "Cannot delete
[field], please update the label identifier field first", but not
"Object metadata does not exist"), even if in practice in the FE users
should not be able to perform an action that will not work (ie should
not be able to save creation of multiple draft versions of the same
workflows).
**FE**
To ease the usage we replaced enqueueSnackBar with enqueueErrorSnackBar
and enqueueSuccessSnackBar with an api that only requires to pass on the
error.
If no displayedErrorMessage is specified then the default error message
is `An error occured.`
This PR attemps at improving sentry grouping and filtering by
- Using the exceptionCode as the fingerprint when the error is a
customException. For this to work in this PR we are now throwing
customExceptions instead of internalServerError deprived of their code.
They will still be converted to Internal server errors when sent back as
response
- Filtering 4xx issues where it was missing (for emailVerification
because errors were not handled, for invalid captcha and billing errors
because they are httpErrors and not graphqlErrors)

In this PR:
- Remove deactivated objects from ActivityTargetInlineCell record picker
- Prevent users to deactivate createdAt, updatedAt, deletedAt fields on
any objects
Still left:
- write unit tests on the assert utils
- write integration tests on field metadata service
- prevent users to deactivate createdAt, updatedAt, deletedAt on FE
## Context
Field metadata service was reusing validators from
validate-**OBJECT**-metadata-input which were throwing ObjectMetadata
exceptions not handled in fieldMetadataGraphqlApiExceptionHandler and
were going to Sentry.
To solve the issue since this validator is associated with both fields
and objects I'm moving the util to the root utils folder of metadata
module and throwing a common metadata user input exception
We call convertExceptionToGraphQLError in the exception handler for http
exceptions but we don't take into account those that already are
graphqlErrors and because of that the logic of convertExceptionToGraphql
is to fallback to a 500.
Now if the exception is a BaseGraphqlError (custom graphql error we
throw in the code), we throw them directly.

Class exception for each metadata module + handler to map on graphql
error
TODO left :
- find a way to call handler on auto-resolvers nestjs query (probably
interceptors)
- discuss what should be done for pre-hooks errors
- discuss what should be done for Unauthorized exception
