This article provides a solution for the issue when you get a getMode() error in the CLI running bin/magento oms:messages:process in the Magento Order Management System (OMS) for Adobe Commerce.

Affected products and versions

This error occurs when using MCOM Connector release 3.1.1 and 3.2.0. It is resolved in MCOM Connector 3.3.0. It is not specific to an MDC or MOM version.


When running the following command in the CLI:

bin/magento oms:messages:process

An error message similar to the following is outputted in the CLI:

<project-id>@<project-id>:~$ php bin/magento oms:messages:process

Processing messages...

PHP Fatal error:Uncaught Error: Call to a member function getMode()
on null in /app/<project-id>/vendor/magento/module-inventory-message-bus/Handler/OnAggregateStockUpdatedSubscriber.php:64

Stack trace:

  #0 [internal function]: Magento\InventoryMessageBus\Handler\OnAggregateStockUpdatedSubscriber->onUpdated(Object(Magento\InventoryMessageBus\Model\Event\OnAggregateStockUpdated))

  #1 /app/<project-id>/vendor/magento/module-service-bus/Message/SingleMessageProcessor.php(81):

  #5 /app/t in /app/<project-id>/vendor/magento/module-inventory-message-bus/Handler/OnAggregateStockUpdatedSubscriber.php
  on line 64


This occurs when the Connector attempts to process magento.inventory.source_management messages. The Connector attempts to process these messages as if they were a magento.inventory.source_stock_management.update message which does require a mode value. Because there is no mode in the magento.inventory.source_mangement messages, the error occurs.


To resolve the problem run the following SQL statement in the CLI which deletes all records in the mcom_api_messages table:

delete from mcom_api_messages;
