Loopback-next: Cannot POST array for multi insert anymore ?

[mathias22osterhagen22]

Steps to reproduce

1. Go on the /explore link of the API
2. Open a POST REST route that is made to add a new model insertion
   Replace the object by an array of the object :
   
3. Click execute

Current Behavior

422 error

Expected Behavior

A success answer with the entries in an array like this I suppose: https://github.com/strongloop/loopback/issues/1275#issuecomment-264409854

[
   {
     "id": "3"
     "name": "array one"
   },
   {
     "id": "4"
     "name": "array two"
   }
]

@mathias22osterhagen22 : You can also use
Promise<People[]> { return await this.peopleRepository.createAll(people) }
@achrinza we can close this issue as its solved..

[achrinza]

Just to summarise,

• @requestBody.array() is needed to allow OpenAPI validation to accept an array of the model.
• yourRepoHere.createAll() is needed to allow the ORM to accept an array of the model.

I'll close this issue due to no reply, and the question being straightforward and well-documented;

Feel free to ping this issue if the problem is not resolved.
