TYPO3 Core

I had this problem in the following versions:

• current master (9.2.0-dev)
• current TYPO3_8-7 branch (8.7.11-dev)
• 8.7.10
  (that's all I tested so far)

Steps to reproduce¶

1. Insert an invalid url (I used http//abc.de/sfdsf) into a content element with the link wizard (external url)
2. Save the content element: exception is thrown

(set configuration presets to "debug" to see exception message)

Exception¶

Exception for 8.7.10:

Uncaught TYPO3 Exception
