[5.0.0-alpha.6]: Invalid field handle on re-install

[WHITE-developer]

What happened?

Description

When trying to setup a clean database with existing project-config, you get an Exception: Invalid field handle: {customFieldHandle} when you have used fields where you have renamed the handle inside a fieldlayout.

cms/src/base/Element.php

Lines 5837 to 5840 in 5dd7cb7

	// ignore if it's not a custom field handle
	if (!isset(CustomFieldBehavior::$fieldHandles[$handle])) {
	return null;
	}

here the CustomFieldBehavior::$fieldHandles is only returning the field handles as defined in settings -> fields, not the handles you have defined in the field layout editors.

Steps to reproduce

1. setup a clean Craft 5 project
2. Create a custom field and map this to an entry type
3. start with a clean DB
4. run ./craft install
5. fill in the required info
6. when applying the existing project config the Exception will be thrown

Expected behavior

Existing project config should be getting applied

Actual behavior

An Invalid field handle exception is thrown

I’m not able to reproduce that. Can you please send your Composer and project config files to [email protected]?

Retried it by first rebuilding config files but still got it,
So started from a completely clean project with no plugins installed and just 1 custom field, but still got it.

When not renaming/rehandling the custom field it all works fine

I've send my project yamls and composer files by mail

Thanks for all the info and the files. I can replicate this issue. It only happens if the field with the changed handle is part of an entry type that is assigned to a single type section. I'm working on a solution for this.

Craft 5.0.0-alpha.9 was just released with a fix for this. Thanks again!
