2. How to fix

1. Open file:

   public function fromDefinition(array $data)
   {
   	
   	$type = $data['type'];
   	
   	if(in_array($type, ["tinytext", "enum"])){
   		$data['type'] = 'text';
   		$type = 'text';
   	}
   	
   	if(in_array($type, ['time', 'mediumint'])){
   		$data['type'] = 'datetime';
   		$type = 'datetime';
   	}
   	
   	if(in_array($type, ['mediumint'])){
   		$data['type'] = 'int';
   		$type = 'int';
   	}
   	
   	if (!isset($this->definitionProcessors[$type])) {
   		throw new \InvalidArgumentException(
   			sprintf("Cannot process definition to array for type %s", $type)
   		);
   	}
   
   	$definitionProcessor = $this->definitionProcessors[$type];
   	return $definitionProcessor->fromDefinition($data);
   }
