Can't save customers after migration Magento 2

Question

After I migrated from Magento 1.9.3.8 to 2.2.5 although I can create new customers I can't edit and save the migrated ones. In admin, I get errors that First Name, Last Name, and other attributes are needed. But in customers, these fields are filled. In

system.log

I get:

[2019-02-16 12:55:39] report.WARNING: Attempt to load value of nonexistent EAV attribute '1163'
                        for entity type 'Magento\Catalog\Api\Data\ProductInterface'. [] []
[2019-02-16 12:55:39] report.WARNING: Attempt to load value of nonexistent EAV attribute '1206'
                        for entity type 'Magento\Catalog\Api\Data\ProductInterface'. [] []

and

[2019-02-16 12:57:27] report.INFO: Broken reference: the 'notification.messages' tries to reorder itself towards 'user', but their parents are different: 'header.inner.right' and 'header' respectively [] []

I managed to remove the mentioned attributes which were product attributes. As continue investigation my problem is a Magento 2.2.5 bug or because Magento 1.9.3.8 was using Amasty customer attributes extension, these customer attributes were migrated to Magento 2 and created this problem.

When I save a migrated customer in admin I get:

"First Name" is a required value.

"First Name" length must be equal to or greater than 1 character.

"Last Name" is a required value.

"Last Name" length must be equal to or greater than 1 character.

"Street Address" is a required value.

"Street Address" length must be equal to or greater than 1 character.

But all these fields are correctly filled.

Can anyone help me what to check, please? I am going crazy here...

Answer 1

I figured out what happened and fixed. Some of the migrated customers had more than one address. In there the

First Name

Last Name

Street Address

was empty.

When I edited the customers and delete that address without fill up these fields I got the error I posted.

I don't if it should work that way but now I fixed it and all customers saved fine.

Answer 2

This happening because of validation file in vendor\magento\framework\File\Uploader and in this function

 private function _setUploadFileId($fileId)
    {
        if (is_array($fileId)) {
            $this->validateFileId($fileId);
            $this->_uploadType = self::MULTIPLE_STYLE;
            $this->_file = $fileId;
        }

comment this following line in the above function:

// $this->validateFileId($fileId);

We can need to override the above function using the following steps: We can override using preference.

1. Create di.xml

   <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
   <preference for="vendor\magento\framework\File\Uploader" type="NameSpace\Customer\Framework\File\Uploader" />
   

2. Create class php file In the given path put your fle NameSpace\Customer\Framework\File\Uploader
