@swentel, are you using the latest version 3.1.x? The variable here already falls back to empty array so the error shouldn't occur: https://git.drupalcode.org/project/custom_field/-/blob/3.1.x/src/Plugin/...

Hmm... maybe its failing here: https://git.drupalcode.org/project/custom_field/-/blob/3.1.x/src/Plugin/.... If you can open a new ticket with some steps to reproduce, it should be an easy fix.

yes, running 3.1.3

Using the debugger, it happens on the formatter settings for a file, using the file_default formatter.

Looking at the code, it looks like this line is the problem: https://git.drupalcode.org/project/custom_field/-/blob/3.1.x/src/Plugin/...

It's totally possible that $settings[$name] does not contain the formatter_settings key, which happens in this case for a file.
