I have updated Drupal core version from Drupal 9.5.11 to Drupal 10.2.6
My configurations:
- Drupal core 10.2.6
- 8.1.28
- Sparkpost 3.0.0-alpha1
There is a non-supported code being used in modules/contrib/sparkpost/src/Plugin/Mail/SparkpostMail.php line no 171
https://www.drupal.org/node/3126004 →
\Symfony\Component\HttpFoundation\File\MimeType\MimeTypeGuesserInterface is deprecated in drupal:9.1.0 and will be removed in drupal:10.0.0, implement \Symfony\Component\Mime\MimeTypeGuesserInterface instead
This prevent sending a test email from admin UI. It works when I replace the lines with guessMimeType().
Error: Call to undefined method Drupal\\Core\\ProxyClass\\File\\MimeType\\MimeTypeGuesser::guess() in Drupal\\sparkpost\\Plugin\\Mail\\SparkpostMail->getAttachmentStruct() (line 171 of /var/www/drupal-cms/web/modules/contrib/sparkpost/src/Plugin/Mail/SparkpostMail.php
Try sending a test email from here: [your_app]/admin/config/services/sparkpost/test
use guessMimeType() instead of guess(), as guess() has been removed from Drupal 10.

This is also resolved in https://www.drupal.org/project/sparkpost/issues/3398176 🐛 The mime type guesser service is changed for d10 Needs review
That issue needs review. Maybe test that patch and mark as rtbc if it works for you?
