Loopback 4 auto generated model with required id failing validation - api

Question

I'm using an automated script that runs an auto-generation model using lb4 cli.
Looks like validation expects id to be provided, but swagger missing it in its schema. Why I can't see the id property in swagger?
PLEASE NOTE! I don't want to modify manually my models
lb4 model activity --dataSource DS --table activity
Created model:
export class Activity extends Entity {
#property({
type: 'string',
required: true,
id: 1,
postgresql: {
columnName: 'id',
dataType: 'uuid',
dataLength: null,
dataPrecision: null,
dataScale: null,
nullable: 'NO',
},
})
id: string;
...
}
When I run the swagger tool and try to POST new activity, it missing the id field and returns the following error:
{
"error": {
"statusCode": 422,
"name": "ValidationError",
"message": "The `Activity` instance is not valid. Details: `id` can't be blank (value: undefined).",
"details": {
"context": "Activity",
"codes": {
"id": [
"presence"
]
},
"messages": {
"id": [
"can't be blank"
]
}
}
}
}
If I add a property id manually, then it throws a validation error:
{
"error": {
"statusCode": 422,
"name": "UnprocessableEntityError",
"message": "The request body is invalid. See error object `details` property for more info.",
"code": "VALIDATION_FAILED",
"details": [
{
"path": "",
"code": "additionalProperties",
"message": "must NOT have additional properties",
"info": {
"additionalProperty": "id"
}
}
]
}
}

Change your #model() by #model({settings: {strict: false}}) and add this line [prop: string]: any; into your model
#model({settings: {strict: false}})
[prop: string]: any;
