I have a problem with my Magento, since I added some customer custom attributes... Here we can see
Fields are display on the create form customer, but when I want to create the account, I have this error
"Fatal error: Uncaught TypeError: Argument 2 passed to Magento\Eav\Model\Attribute\Data\Text::validateLength() must be of the type string, null given"
So, I try to debug the file vendor/magento/module-eav/Model/Attribute/Data/Text.php and on line 80, before the call of the function
validateLength(\Magento\Eav\Model\Attribute $attribute, string $value), for one call the $value is NULL.
How to fix this ?
Thanks (I'm a beginner in Magento ;)
