TYPO3 Core

When a table does not exist because I forgot to create it, I get the following error in a form finisher:

Call to a member function getMessage() on null

in /var/www/html/vendor/typo3/cms-extbase/Classes/Persistence/Generic/Storage/Typo3DbBackend.php line 90

In this line $e->getPrevious(), which is nullable is expected to always exist.

I was able to get a helpful error message by changing the line to

throw new SqlErrorException($e->getPrevious()?->getMessage()??$e->getMessage(), 1470230766, $e);
