I use a node flag with an additional field (date). In a views list i display all nodes of a nodetype with the flag link field and the date field which i can set with the flag.
When ich click on the flag link the confirmation page with the datefield appears. I set the right date and save.

Now i get the message "The website encountered an unexpected error. Please try again later." and in the recent log messages this two error messages appears. (screenshots)

When i click on the back-button of the browser and set the date again i get no error and the function work correctly.

How can i fix that?

Drupal 7.54
Flag 7.x-3.9

Does this also happen when you use the flag link on a node, rather than in a View?

(BTW, screenshots are only useful when you're showing something that's not text, such as a styling or a layout problem. Here, they're actually not a good idea, as I can't properly read the error text in your screenshots, and more importantly, I can't copy-paste it to search for it in the codebase. Please copy and paste error messages into issues, rather than taking screenshots.)
