Magento 2.3.3 declarative schema column type json

I want to create One table model using declarative schema having one column type as json.

    < ?xml version="1.0" ?>

    
            
        
            
        

I captured following error:-

/var/www/public_html/vendor/magento/framework/Setup/Declaration/Schema/SchemaConfig.php:82:
string(412) "The XML in file "/var/www/public_html/app/code/Levosoft/Partpicker/etc/db_schema.xml" is invalid:
Element 'column', attribute '{http://www.w3.org/2001/XMLSchema-instance}type': The QName value 'json' of the xsi:type attribute does not resolve to a type definition.
Line: 9

The error shows that yet magento had not added support for json type.

Any proper work around? Other then I `alter type later via sql`

To check declarative schema is working properly you have to run following command:

php bin/magento setup:db-declaration:generate-whitelist --module-name=Textmimedia_Partpicker

If no error in script it will generate whitelist file else no error will be displayed & file not generated.
To check its error you have to update following code in core file (/public_html/vendor/magento/framework/Setup/Declaration/Schema/SchemaConfig.php) for testing:

public function getDeclarationConfig()
    {
        try {
        $schema = $this->schemaFactory->create();
        $data = $this->readerComposite->read(FileResolverByModule::ALL_MODULES);
        $this->declarativeSchemaBuilder->addTablesData($data['table']);
        $schema = $this->declarativeSchemaBuilder->build($schema);
        return $schema;
        } catch (Exception $e) {
            var_dump($e->getMessage());exit;
        }
    }
