Upgrade failed no default template exists with this key

[Alfonso_Fernandez]

I’m upgrading from from 3.3.0.14 to 3.4.0.1 but i get the error message

[downgrade for "APP\migration\upgrade\v3_4_0\I7796_UpdateCrossrefSchema" unsupported: Downgrade not supported] 
ERROR: Upgrade failed: DB: Tried to install email template as an alternate to `DISCUSSION_NOTIFICATION_SUBMISSION`, but no default template exists with this key.

Have you had this problem, how can I complete the upgrade?

Hi @Alfonso_Fernandez

This thread has an user reporting the same issue you are dealing with:

Error during upgrade from 3.3.0.13 to 3.4.0.1 - Unsupported assoc_type in the event log: 515

I can confirm that I am encountering the same error. I am upgrading from 3.3.0.14 to 3.4.0.1. Here is the error that I see 2023-06-26 16:28:49 [downgrade for "APP\migration\upgrade\v3_4_0\I7796_UpdateCrossrefSchema" unsupported: Downgrade not supported] ERROR: Upgrade failed: DB: Tried to install email template as an alternate to `DISCUSSION_NOTIFICATION_SUBMISSION`, but no default template exists with this key. If I execute sudo php tools/upgrade.php upgrade again, I get the following error…

Best,

Same problem for me (from 3.2… to 3.4.0.1) and no solution found.

I have solved this issue by inserting a record with ‘DISCUSSION_NOTIFICATION_SUBMISSION’ key into this table ‘email_templates_default_data’ in the database, before starting the upgrade.
