craft\helpers\Cp::elementChipHtml(): Argument #1 ($element) must be of type craft\base\ElementInterface, null given error when feed mapping reference an default asset which is deleted

[jamesmacwhite]

Description

If you have a feed with a field mapping that references an asset as a default value for an asset field. If you delete the referenced default asset it causes the following error when loading the feed mapping page:

craft\helpers\Cp::elementChipHtml(): Argument #1 ($element) must be of type craft\base\ElementInterface, null given

This causes the Feed Me field mapping CP path to throw a Server Error, meaning you cannot edit the field mapping data through the CP anymore.

In order to fix this, I had a do a DB migration which modified the fieldMapping column to remove the default asset ID data, so it could be edited again resaved to update the data properly.

Steps to reproduce

1. Serup a feed which has an asset field
2. Set a default asset in the feed
3. Delete the asset
4. Load the feed mapping and get a Server Error.
