Fatal Error after upgrade TYPO3 to the version 10.4.10

[vruescas]

After upgrade TYPO3 to the version 12.4.10 i get the following error message:

Fatal error: Declaration of In2code\Powermail\Condition\PowermailConditionFunctionsProvider::getFunctions() must be compatible with Symfony\Component\ExpressionLanguage\ExpressionFunctionProviderInterface::getFunctions(): array in /var/www/html/vendor/in2code/powermail/Classes/Condition/PowermailConditionFunctionsProvider.php on line 20

I have this after upgrading to version 12.0.3

Downgrade symfony/expression-language to ^6.4 until a fix has been made in powermail

Or patch powermail by replacing in In2code\Powermail\Condition\PowermailConditionFunctionsProvider line 20: public function getFunctions()

with this: public function getFunctions(): array

Please update to the current powermail version.

Fixed with 12.1.0 (current version is 12.3.5)
