error when synchronizing products

[florent*]

Hello,

I am using a service that synchronizes prestashop with my ERP.

When we run it we get this error : 

[PHP Notice #8] Trying to access array offset 
on value of type null 
(/...classes/webservice/WebserviceOutputBuilder.php, line 716)

and 

[PHP Notice #8] Trying to access array offset 
on value of type null 
(/.../classes/webservice/WebserviceOutputBuilder.php, line 719)

 

line 716 is : $field['value'] = $object_assoc['id'];

line 719 is : $field['value'] = $object_assoc[$field_name];

foreach ($fields_assoc as $field_name => $field) {
            if (!is_array($this->fieldsToDisplay) || in_array($field_name, $this->fieldsToDisplay[$assoc_name])) {
                if ($field_name == 'id' && !isset($field['sqlId'])) {
                    $field['sqlId'] = 'id';
                    $field['value'] = $object_assoc['id'];
                } elseif (!isset($field['sqlId'])) {
                    $field['sqlId'] = $field_name;
                    $field['value'] = $object_assoc[$field_name];
                }
                $field['entities_name'] = $assoc_name;
                $field['entity_name'] = $resource_name;

                if (null !== $this->schemaToDisplay) {
                    $field['synopsis_details'] = $this->getSynopsisDetails($field);
                }
                $field['is_association'] = true;
                $output .= $this->setIndent($depth - 1) . $this->objectRender->renderField($field);
            }
        }

 

Does anyone please know how to fix it?

for me I solved the problem by changing the version of PHP.

I hope this will help you.
