foreach ($this->metaProperties as $metaName => $origName) {
    $value = $attribute->getDataUsingMethod($origName);
    $meta[$code]['arguments']['data']['config'][$metaName] = ($metaName === 'label') ? __($value) : $value;
    if ('frontend_input' === $origName) {
        $meta[$code]['arguments']['data']['config']['formElement'] = isset($this->formElement[$value])
            ? $this->formElement[$value]
            : $value;
    }
}

SELECT * FROM `eav_attribute` WHERE 'telephone' = attribute_code;

Solution

DELETE FROM customer_eav_attribute WHERE 165 = attribute_id;
DELETE FROM eav_attribute WHERE 165 = attribute_id;

I had same error.
I had this error with multiple attributes.
I fixed by open attribute from Stores->Attributes->Products and save again.
This helped me, I hope this will help you too.
