2.4.0 Class Temando\Shipping\Model\Source\PackagingType does not exist

[haxor211]

I have ran the query in my database and removed 3 rows.. the problem still persists, what do I do?? I dont want to enable this useless module.

I also used the new module in 2.4.0 "Temando_ShippingRemover" and ran setup:upgrade, still doesnt work!!

I also tried deleting the attributes starting with "ts_%" in datatbase, this doesnt help either!!!!

The error "Exception #0 (ReflectionException): Class Temando\Shipping\Model\Source\PackagingType does not exist" is still here. Help me out please its driving me insane

I have searched my whole database for entries like "temando" or "ts_*" nothing to be found... the biggest shock to me is that I have attributes such as "ts_dimensions_height" in my backend in attributes section, yet I cant find it anywhere in the database!!!

Can someoone help me and tell me whats going on here with this shitty module?

Magento 2 Core has a core issue. When the source model of the EAV class from the Database does not exist magento throws

ReflectionException

Exception #0 (ReflectionException): Class "**\Model\Config\Source***\Options" does not exist

/var/www/html/magento/vendor/magento/framework/Code/Reader/ClassReader.php

 public function getConstructor($className)
    {
        $class = new ReflectionClass($className); <-- Exception happens here 

however, it has logic to tell you exactly what attribute Model is missing

/var/www/html/magento/vendor/magento/module-eav/Model/Entity/Attribute/AbstractAttribute.php

public function getSource()
    {
        if (empty($this->_source)) {
            if (!$this->getSourceModel()) {
                $this->_source = $this->_getDefaultSourceModel();
            } else {
                $this->_source = $this->getSourceModel();
            }
        
            if (!$source) {
                throw new LocalizedException(
                    __(
                        'Source model "%1" not found for attribute "%2"',
                        $this->getSourceModel(),
                        $this->getAttributeCode()
                    )
                );
            }

but this logic never happens because it is an Exception(ReflectionException) not a bool value

you need to add this code and check exception

public function getSource()
{
if (empty($this->_source)) {
if (!$this->getSourceModel()) {
$this->_source = $this->_getDefaultSourceModel();
} else {
$this->_source = $this->getSourceModel();
}
try {
$source = $this->_universalFactory->create($this->_source);
} catch (\ReflectionException $e) {
$source = false;
}
if (!$source) {
throw new LocalizedException(
__(
'Source model "%1" not found for attribute "%2"',
$this->getSourceModel(),
$this->getAttributeCode()
)
);
}

then an exception will be self-explained:

Exception #0 (Magento\Framework\Exception\LocalizedException): Source model "*****\Model\Config\Source*\Options" not found for attribute "some_attribute"

Please fix it ASAP.
