TYPO3 Core

If (e.g.) a powermail pluin is on a page in TYPO3 8.7 and the FlexForm is filled with some plugin settings (email addresses of the receiver, etc...). The list module can throw an exception, if the field pi_flexform should be displayed as additional column.

Exception message:

NAMEPREP: Prohibited input U+0000000A
in Mso\IdnaConvert\Punycode::namePrep()

• Add a FlexForm string to any content element in tt_content.pi_flexform (see below) or simply add a powermail plugin with some settings
• Switch to list module
• Click on the title of the table "Page Content"
• Select Plugin Options to be shown in addition in the list view table and then submit
• An exception is given

Example FlexForm:
