[FLOW3-general] An error occurred while trying to call nameAction()

[David Sporer]

Hey Guys,

 

I know this thing has been described somewhere but I just can't find it.

When I'm sending my new form and a validation error occurs I get this
flashmessage: 

An error occurred while trying to call
Passbooks\PassbookPasses\Controller\PassKeyController->createAction()

 

The "right" error messages are shown as expected (Name: this property is
required etc.).

 

How can I hide this error message?

 

Best regards

David
