TYPO3 Core

In our log files we see those erros a few times a day:

(1/1) #1476107295 TYPO3\CMS\Core\Error\Exception
PHP Warning: foreach() argument must be of type array|object, null given in 
typo3_src/typo3_src-11.5.30/typo3/sysext/extbase/Classes/Mvc/Controller/MvcPropertyMappingConfigurationService.php

This is an extbase / fluid list view.

Here is a sample request.

PCP-Code:
MvcPropertyMappingConfigurationService.php : Line 145

$trustedProperties = json_decode($serializedTrustedProperties, true);
foreach ($trustedProperties as $propertyName => $propertyConfiguration) {
    if (!$controllerArguments->hasArgument($propertyName)) {
        continue;
        }
    $propertyMappingConfiguration = $controllerArguments->getArgument($propertyName)->getPropertyMappingConfiguration();
    $this->modifyPropertyMappingConfiguration($propertyConfiguration, $propertyMappingConfiguration);
}

In this case $trustedProperties is null

Maybe this should be checked before?

$trustedProperties = json_decode($serializedTrustedProperties, true);
if ($trustedProperties && is_array($trustedProperties)){
  foreach ($trustedProperties as $propertyName => $propertyConfiguration) {
      if (!$controllerArguments->hasArgument($propertyName)) {
          continue;
          }
      $propertyMappingConfiguration = $controllerArguments->getArgument($propertyName)->getPropertyMappingConfiguration();
      $this->modifyPropertyMappingConfiguration($propertyConfiguration, $propertyMappingConfiguration);
  }
}
