Add Amqp as a dependency for ProductAlert

[Bartiema]

Summary (*)

If the amqp module is not installed in your magento 2.4.4 instance and you want to use the ProductAlert module functionality you will never be able to send alert emails because when the cronjob catalog_product_alert is run there will be a critical error with the message: "Publisher 'product_alert' is not declared"

Steps to reproduce

• Set a specific product to be out of stock
• Go to frontend and subscribe to product inventory alert, so the customer gets notified as soon as the product is back in stock
• Make sure, that the customer alert appears in the product view in the admin area in the Product Alerts section.
• Put the product back to stock
• To manually run this cron job from the CLI you could do this

mysql -e "INSERT INTO cron_schedule ( job_code, scheduled_at ) VALUES ( 'catalog_product_alert', CURENT_TIMESTAMP );" && php bin/magento cron:run

• You will directly get the error message CRITICAL: Publisher 'product_alert' is not declared. [] []
• Activate Magento_Amqp and do the same again
• The error will be gone

Examples (*)

.CRITICAL: Publisher 'product_alert' is not declared. [] []
is the error you can find in debug.log after running bin/magento cron:run when the cronjob catalog_product_alert is trying to send an alert.

Proposed solution

Add the amqp module as a dependency for the ProductAlert module, both in composer and in the module.xml

@Bartiema

Thanks for reporting the issue.

As you mentioned that "amqp module is not installed " so, could you please confirm if you uninstalled or disabled the module "module-amqp" in config.php file then run the cron manually from terminal so you got that exception.

Please provide the exact steps to reproduce the same and share the screenshots so we can try to reproduce the same at our end.

Thanks,

@engcom-Echo , I can verify the issue still persists on Magento 2.4.5-p1.
You can reproduce it, like @Bartiema said, by disabling Magento_Amqp and then doing the following steps:

• Set a specific product to be out of stock
• Go to frontend and subscribe to product inventory alert, so the customer gets notified as soon as the product is back in stock
• Make sure, that the customer alert appears in the product view in the admin area in the Product Alerts section.
• Put the product back to stock
• Run bin/magento cron:run
• You will directly get the error message CRITICAL: Publisher 'product_alert' is not declared. [] []
• Activate Magento_Amqp and do the same again
• The error will be gone

I can confirm the same situation.

Never needed the amqp module in the past. But it appears with v2.4.5-p1 (or maybe one of the versions prior) it is required??? Can't find any documenation to support that, but appears to be the case if you want to send product alerts...

[APanteleychuk]

I can confirm the same situation too.

@engcom-Echo This issue is closed, but reproducible on 2.4.6-p2

Other modules do not need to have Magento_Amqp enabled, like Magento_Catalog with the topic product_action_attribute.update or Magento_SalesRule with topic sales_rule.codegenerator. Both modules have files etc/queue_publisher.xml and etc/queue_topology.xml, whereas Magento_ProductAlert does not provide these files.
Might there be a problem?
