Fatal error: EmailValidator::isValid must be compatible with Egulias\EmailValidator\EmailValidator

Could you please share with us the steps you followed to update the codebase?

Same here.
Upgrade to Drupal 8.7 done through SFTP upload of the core folder. Other folders untouched.
Multisite setup.

And after testing, I can confirm that in my case, it was caused by not updating the "vendor" directory of Drupal.

@cilefen, I updated using this reference:

composer update drupal/core --with-dependencies
drush updatedb
drush cr

Do you have any recommendation/idea?

Have you compared the files in question to a clean Drupal download?

Some platforms have Zend opcache configured in a way that prevents re-reading changed classes. In that event restarting the web server may sort it out. Have you examined which files changed in the update?

I had the same issue.
composer update drupal/core
... did not do much.
I had to remove the vendor directory and rebuild it using:
composer install -vvv
That fixed the issue (make sure that your composer.json has all the requirements).

I am closing this support request because there have been no recent comments.

The Drupal Core issue queue is not the ideal place for support requests. Consider other sources of support.

I'm getting the following error when attempting to reset a password at:

Argument 1 passed to Egulias\EmailValidator\EmailValidator::isValid() must be of the type string;

I am using Drupal 9.3.2 along with Agigee Edge 2.0.1.

@jjmackow That looks like the smtp contrib module not calling the validator according to its current API, which does not accept null.

Drupal\Component\Utility\EmailValidator->isValid() (Line: 251)
Drupal\smtp\Plugin\Mail\SMTPMailSystem->mail() (Line: 311)

I suggest taking that up with that project.

Also @jjmackow, and sorry for the noise, the thing you reported above is not the same as the one people reported in this issue.

@jjmackow did you solve your error? because I have the same error.

On password reset action happens. Drupal 9.3.2

I get this error with a password reset for Drupal 9.3.3 as well.

@parashutiki/@jjmackow were you able to fix this?

Saw this error with password reset, while we are required to use the SMTP Module but we essentially had no SMTP configuration like a null from address. Make sure your site can send an email first, then try the password reset process again.

Hi,

I have the same issue on Drupal 9.3.3 when I want to unlock an user.

Here are the apache logs (I have only these error logs, there's no error on admin Drupal interface, I just have a white screen).

[Mon Jul 25 13:32:41.606799 2022] [php7:error] [pid 15134] [client ...] PHP Fatal error: Declaration of Egulias\\EmailValidator\\Validation\\MessageIDValidation::isValid(string $email, Egulias\\EmailValidator\\EmailLexer $emailLexer): bool must be compatible with Egulias\\EmailValidator\\Validation\\EmailValidation::isValid($email, Egulias\\EmailValidator\\EmailLexer $emailLexer) in /var/www/html/vendor/egulias/email-validator/src/Validation/MessageIDValidation.php on line 23, referer: http://.../admin/people

I have checked that I can send an email.

Thanks.
