After I Import any kind of data and hit the preview button I always get an error in the result column:

The Import seems to work without issue however

I have the same issue.

I get the same error while importing any usergroup.

TYPO3: 11.5.19
PHP: 8.1

I'm trying to import data from TYPO3 9.5 to 11.5 and I see the same error message in preview window. The actual import doesn't work and stops with the following error message:

503
Oops, an error occurred!

Argument 1 passed to TYPO3\CMS\Impexp\Import::getReferenceDefaultValue() must be of the type array, null given, called in [...]/sysext/impexp/Classes/Import.php on line 1042

The 'ERROR: One of the inputs were not an array!' occurs when you attempt to import something - both preview and real import - and you have:

• Update records = false
• Do not show differences in records = false

The import module then tries to show differences, but there are no differences to be shown since your import will create new records. The error disappears when you check 'Do not show differences in records'. It looks like you can ignore this error (although it is definately confusing).

Note: The exported page does not exist yet in the new installation.

In this case $databaseRecord is null and the error message gets triggered.
