Hello @manhtranisobar,

Thank you for the report and collaboration!

Tried to reproduce this issue on 2.4-develop, but in our case it is not reproducible.
Created a AFTER INSERT custom trigger to store table with name trg_test_mview, please take a look at the screenshot below:

With the custom trigger added, while running bin/magento setup:upgrade we did not see any error.

Please let us know if we are missing anything.

Thank you.

Hi @engcom-November

It is strange,
If you can use to debug logic of function \Magento\Framework\Mview\TriggerCleaner::removeTriggers then you can see It will try to create a dummy view with old_view id then It will be loaded by vendor/magento/framework/Mview/View/Subscription.php:357 so error appeared.

It see there are 2 conditions to error appear:

• A custom trigger with name format is difference Mview triggers
• This custom trigger is created for tables, that are used by Mview config
  This is exception stack:

Warning: Trying to access array offset on value of type null in vendor/magento/framework/Mview/View/Subscription.php on line 357

Hello @manhtranisobar,

Thank you for the quick response!

As you mentioned, This custom trigger is created for tables, that are used by Mview config.
Created a custom trigger for a table that already has triggers from mview configuration, with this we were able to reproduce this issue.

Please take a look at the screenshot below:
Added a custom trigger to catalog_product_entity table, which already has 3 triggers.

While running setup:upgrade we got the error

Hence confirming the issue.

Thank you.
