preg_match() type error when setting default for asset field

[siffring]

Description

When running an entry import that has a default asset set for an asset field I get this error:

**preg_match(): Argument #2 ($subject) must be of type string, array given**

It's from line 133 of feed-me/src/fields/Assets.php

Steps to reproduce

1. Set a default file for an asset field in an entry import
2. Run the import

If you remove the default file setting the import works.

Additional info

• Craft version: 4.2.8
• PHP version: 8.1.11
• Database driver & version: MySQL 8.0.26
• Plugins & versions: FeedMe 5.0.4

Hi, thanks for reporting. I need help replicating this issue. I tried a JSON feed for entry import with add & update strategy; my asset field has access to all volumes and is a standalone field (not embedded in a matrix or anything like that). Could anyone please give me some more info on how I can reproduce this?

@i-just I don't have that environment setup any more, but as I recall I was just trying to assign a default image to an asset field. I don't recall if the asset was in an Matrix or stand alone.

My source was a Google Sheet if that matters.

Thanks for the info. The source shouldn’t matter here.

I can replicate this if I map the assets field to a value from a feed, have some empty values in my feed and then still select a default value.

We’ll discuss this behaviour internally.
