impossible to upgrade 4.5.0 -> 4.5.1

[piomio]

Hello,
When I try to upgrade to 4.5.1 from 4.5.0, I get an error:

Error while rebuilding database. See log file for details.

In the logs:

[2017-04-12 17:37:08] Espo.ERROR: Fault to rebuild database schema. Details: Unknown database type enum requested, Espo\Core\Utils\Database\DBAL\Platforms\MySqlPlatform may not support it. [] []
[2017-04-12 17:37:08] Espo.ERROR: API [POST]:/:controller/action/:action, Params:Array (     [controller] => Admin     [action] => runUpgrade ) , InputData: {"id":"58ee65bfcb21a"} - Error while rebuilding database. See log file for details. [] []
[2017-04-12 17:37:08] Espo.ERROR: Display Error: Error while rebuilding database. See log file for details., Code: 500 URL: /api/v1/Admin/action/runUpgrade [] []

Thanks in advance for your help.

Thanks, but doesn't work. I get the following error when trying to rebuild the database from the admin panel:

[2017-04-24 10:23:06] Espo.ERROR: Uncaught Exception Error: "Call to a member function hasDoctrineTypeMappingFor() on null" at /home/infomast/crm/application/Espo/Core/Utils/Database/Schema/Schema.php line 188 {"exception":"[object] (Error(code: 0): Call to a member function hasDoctrineTypeMappingFor() on null at /home/infomast/crm/application/Espo/Core/Utils/Database/Schema/Schema.php:188)"} []

I replaced the original code in Schema.php with this one, is it right?

    protected function initFieldTypes()
    {
        foreach($this->fieldTypePaths as $path) {

            $typeList = $this->getFileManager()->getFileList($path, false, '\.php$');
            if ($typeList !== false) {
                foreach ($typeList as $name) {
                    $typeName = preg_replace('/Type\.php$/i', '', $name);
                    $dbalTypeName = strtolower($typeName);

                    $filePath = Util::concatPath($path, $typeName . 'Type');
                    $class = Util::getClassName($filePath);

                    if( ! Type::hasType($dbalTypeName) ) {
                        Type::addType($dbalTypeName, $class);
                    } else {
                        Type::overrideType($dbalTypeName, $class);
                    }

                    $dbTypeName = method_exists($class, 'getDbTypeName') ? $class::getDbTypeName() : $dbalTypeName;

                    $this->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping($dbTypeName, $dbalTypeName);
                }
            }
        }
        if (!$databasePlatform->hasDoctrineTypeMappingFor('enum')) {
            $databasePlatform->registerDoctrineTypeMapping('enum', 'string');
        }
 }

Thanks.
