New employee getting error message when trying to book hotel

[MTanoJKA]

Every time our new employee, Kevin Kania tries to book a hotel, he gets the error message 'Failed to reserve room' on the app and on the website, unable to book hotel due to the following error: "option invalid for chain --/FT-". Is there something that needs to be updated in his profile? What does this error message mean? When his coworkers try to book the same hotel using the same steps it works for them.

@MTanoJKA is this still an issue? I've posted the error internally to see if anyone can tell me what it means. 

I'll let you know if I hear anything.

I received the same error message, but just with one hotel at the end of the booking process. My colleague did not have an issue booking the same room.

I have booked multiple hotel rooms before and could also book a room with another hotel for the same city and period. 

Any idea for a solution?
