How to fix Laravel Trailing Data Exception ?

Setting timestamps to false means you are going to lose both created_at and updated_at whereas you could set both of the keys in your model.

Case 1:

You have created_at column but not update_at you could simply set updated_at to false in your model

class ABC extends Model {

const UPDATED_AT = null;

Case 2:

You have both created_at and updated_at columns but with different column names

You could simply do:

class ABC extends Model {

const CREATED_AT = 'name_of_created_at_column';
const UPDATED_AT = 'name_of_updated_at_column';

Finally ignoring timestamps completely:

class ABC extends Model {

public $timestamps = false;

Trailing data is a Carbon error, it’s because you probably use Postgres and your date returns milliseconds.

“created_at” => “2018-04-19 07:01:19.929554”

You can add the following method to your (base) model.

public function getDateFormat()
{
     return 'Y-m-d H:i:s.u';
}

The ideal image size for Twitter Cards is 800px by 418px, a 1.91:1 ratio. For App Cards, you can go with 800px by 800px for a 1:1 ratio.
Videos can also be used in Twitter Cards. The recommended size for Website Card videos is 1200px by 1200px, or 1:1 aspect ratio. For App Card and Direct Message Card, the recommended size is 640px by 360px for a 16:9 ratio, or 360px by 360px for a 1:1 ratio.
Twitter supports images that are JPEG or PNG format; no GIFs are allowed here.
For best results, make sure your image is no larger than 3 MB.
The approved file types are MP4 or MOV, ideally less than 30 MB in size, and no more than 1 GB when it comes to videos.
Twitter advises a short video for these cards, so aim to keep it less than 15 seconds.
For videos, place your logo in the upper left-hand corner.
All Website Card videos are required to have closed captioning or text overlays.
