Formatting date on models to ISO 8601 gives error

[joelperry93]

I'm trying to format the date properties on my models to conform to ISO 8601 by using the $dateFormat property on the model classes. When I override this property in the models, I get a "bad request" error on all requests

{
    "errors": [
        {
            "status": 400,
            "title": "Bad Request",
            "detail": "Request could not be served."
        }
    ]
}

Is modifying this property the best way to get ISO 8601? And how do I track down the actual issue here? There isn't anything in storage/logs/laravel.log. Is there a seperate log?

Thanks

I had an issue that may be related to this. I have to specify custom timestamps in my model. After a bit of digging I found where the UPDATED_AT field was being set in the JsonApiTrait.php I changed the line that sets the updated_at property in both put/patch ops to:

$data['attributes'][$model::UPDATED_AT] = Carbon::now()->format($model::getDateFormat());

Everything appears to be working on my end. I created a pull request.
