The wrong code is here:
*/
if (isset(
$this->_data['attribute_code']
) && !\Zend_Validate::is(
$this->_data['attribute_code'],
'StringLength',
['max' => self::ATTRIBUTE_CODE_MAX_LENGTH]

throw new LocalizedException(
__('An attribute code must be fewer than %1 characters.', self::ATTRIBUTE_CODE_MAX_LENGTH)

$numberFormatter = new \NumberFormatter($this->_localeResolver->getLocale(), \NumberFormatter::DECIMAL);
$defaultValue = $numberFormatter->parse($defaultValue);
if ($defaultValue === false) {
and here:
if (isset(
$data['attribute_code']

$data['attribute_code'],
'StringLength',
['max' => $attributeCodeMaxLength]
)
) {
throw new LocalizedException(

return true;
}
/**
* Add attribute to an entity type

The message An attribute code must be fewer than %1 characters. is wrong because the length equals to \Magento\Eav\Model\Entity\Attribute::ATTRIBUTE_CODE_MAX_LENGTHZend_Validate_StringLength validator used:
if ($this->_encoding !== null) {
$length = iconv_strlen($value, $this->_encoding);
} else {
$length = iconv_strlen($value);
}
if ($length < $this->_min) {
$this->_error(self::TOO_SHORT);
}
if (null !== $this->_max && $this->_max < $length) {
$this->_error(self::TOO_LONG);
}
if (count($this->_messages)) {
return false;
} else {
return true;
