Mismatched entity and/or field definitions

Same here.

After updating to 3.0.0-beta3 from 3.0.0-beta2 I am also facing the same problem.

Same happened to me after updating from 3.0.0-beta2.

Kindly request to support to solve this issue.

Me too. Also ran database update on drush. No errors reported. A 2nd db update reports nothing to do. Even forcing a rerun of the simplenews_update_830008() hook like the following, does nothing:

$drush php
>>> require "/var/www/web/modules/contrib/simplenews/simplenews.install";
=> 1
>>> simplenews_update_830008();
=> null

It's annoying, but certainly, not critical..

From the screenshot, I think that @zenimagine is running his system in French, and translated the strings back to English. Unfortunately, these do not correspond to the actual strings provided by Drupal. I'm updating the issue summary with the English strings provided by Drupal.

This was one probable reason why a duplicated issue with the right title was created in the meantime (#3316797: Mismatched entity and/or field definitions).

This should fix the problem, at least it did for me. I chose to set required to false, in order to respect the same database definition from beta2.

Caused by #3266989: Subscriber does not declare uuid entity key. simplenews_update_830008() should work but doesn't.

See https://www.drupal.org/node/2554097, and search for // @todo The above should be enough,
