# Introduction
From the moment replaced the FieldMetadataInterface definition to:
```ts
import { FieldMetadataType } from 'twenty-shared/types';
import { FieldMetadataEntity } from 'src/engine/metadata-modules/field-metadata/field-metadata.entity';
export type FieldMetadataInterface<
T extends FieldMetadataType = FieldMetadataType,
> = FieldMetadataEntity<T>;
```
After this PR merge will create a new one removing the type and
replacing it to `FieldMetadataEntity`.
Did not renamed it here to avoid conflicts on naming + type issues fixs
within the same PR
## Field metadata entity RELATION or MORPH
Relations fields cannot be null for those field metadata entity instance
anymore, but are never for the others see
`packages/twenty-server/src/engine/metadata-modules/field-metadata/types/field-metadata-entity-test.type.ts`
( introduced TypeScript tests )
## Concerns
- TS_VECTOR is the most at risk with the `generatedType` and
`asExpression` removal from interface
## What's next
- `FielMetadataInterface` removal and rename ( see introduction )
- Depcrecating `ObjectMetadataInterface`
- Refactor `FieldMetadataEntity` optional fiels to be nullable only
- TO DIG `never` occurences on settings, defaultValue etc
- Some interfaces will be replaced by the `FlatFieldMetadata` when
deprecating the current sync and comparators tools
This PR does not produce any functional changes for our users. It
prepares the branches for workflows by:
- decommissioning `output` and `context` fields or `workflowRun` records
and use newly created `state` field from front-end and back-end
- use `stepStatus` computed by `back-end` in `front-end`
- add utils and types in `twenty-shared/workflow` (not completed, a
follow-up is scheduled
https://github.com/twentyhq/core-team-issues/issues/1211)
- add concurrency to `workflowQueue` message queue to avoid weird branch
execution when using forms in workflow branches
- add a WithLock decorator for better dev experience of
`CacheLockService.withLock` usage
Here is an example of such a workflow running (front branch display is
not yet done that's why it looks ugly) ->

This PR does not produce any functional change
First step of the workflow branch feature
- add gather `workflowRun.output` and `workflowRun.context` into one
column `workflowRun.runContext`
- add a command to fill `runContext` from `output` and `context` in
existing records
- maintain `runContext` up to date during workflow runs
