6.4.17

Description

When sending an email using Sendgrid and the "category" field as a string, the webhook parser fails :

AbstractMailerEvent::setTags(): Argument #1 ($tags) must be of type array, string given, called in vendor/symfony/sendgrid-mailer/RemoteEvent/SendgridPayloadConverter.php on line 54

According to Sendgrid's documentation (https://www.twilio.com/docs/sendgrid/for-developers/tracking-events/event#json-objects) :

category - Categories are custom tags that you set for the purpose of organizing your emails. If you send single categories as an array, they will be returned by the webhook as an array. If you send single categories as a string, they will be returned by the webhook as a string.

How to reproduce

• Have a Symfony app with the sendgrid webhook installed
• Send an email with the sendgrid category as a string

=> the SendgridPayloadConverter should fails when calling setTags (which expects an array)
