Class "PKP\notification\PKPNotification" not found

[evici]

Describe the issue or problem
Creating submission flow breaks on final step.

Steps I took leading up to the issue

1. Go to create submission fill in all fields

2. On final step click ‘Submit‘, which opens modal to confirm or cancel

3. By clicking submit button in modal to confirm

4. See error

   Here is the trace of problem

   Request URL

   https://ojs.test/index.php/test2025/api/v1/submissions/43130/submit

   Request Method

   POST

   Status Code

   400 Bad Request

   Remote Address

   127.0.0.1:443

   {

   “error”: “The GET method is not supported for route test2025/api/v1/submissions/43130/submit. Supported methods: PUT.”

   }

   Tracing further i noticed another error:
   Class “PKP\notification\PKPNotification” not found

**Fix applied
**
Created a class PKPNotification.php in lib/pkp/classes/notification/

<?php namespace PKP\\notification; class PKPNotification extends Notification { } This eliminated errors on submission** OJS version:** 3.5.0-1

Hi @evici,

Were you able to capture from the error message where the PKPNotification class was referred to? Rather than creating a new PKPNotification class where there shouldn’t be one, it would be better to update the calling code to refer to Notification instead.
