Gravity Form data not saving when DEBUG set to True

Hi, i do program with DEBUG set to trye to catch all errors, when saving a GF i get the following E_NOTICE error


Error: Array to string conversion
File: contact-form-7-to-database-extension\CFDBIntegrationGravityForms.php
Line: 121

118 case 'list' :
119 $list = unserialize($entry[$fieldId]);
120 if ($list) {
121 $postedData[$fieldName] = implode('|', array_values($list));

For now i did solve this error by replacing line 121 with the following:


$postedData[$fieldName] = '';
foreach ($list as $k => $v) {
$postedData[$fieldName] .= is_array( $v ) ? implode('|', $v) : $v . '|';
}
