TYPO3 Core

I accidently called findBy with

$user = $this->userRepository->findOneBy(['feUserId', $this->getFeUserId()]);

and the findby method was passing down the column as integer "0" all the way down to the
Typo3DbQueryParser where in line 553 there is a type error that the property name is not a string.

It took me a while of debugging why this type error was triggered. While the code I used was wrong, this
error is easy to make and a check for types should be applied earlier I feel.

The error was:

str_contains(): Argument #1 ($haystack) must be of type string, int given
