Error 500 on Advanced Pack Demo

[Glenn Chapman]

Hello, I am currently trialling the advanced pack demo and I keep getting an Error500 when I amend a contact. Not sure how to get resolved, or what's going wrong. Thanks Glenn

You need to provide some sort of information Glenn, it impossible for anyone to help you like this.

For a how to here: https://docs.espocrm.com/administrat...oubleshooting/

You would just need to try a various thing to get it working yourself, or people will be giving you general hit or miss guide without more information

Hello!

The problem was in the Workflow Actions for Creating Record > Parent field (attached the screenshot). This field was empty, that's why the error occured.
Also, part of a workflow was to send a task which is assigned to the changed contact and the Parent field to be the same as the changed contact.
To do this, we can use this formula:

parentId == contactId
