[Error "No route passed" - developing an bootstrap 4 theme]

Hi there,

today I started developing a theme based on Bootstrap 4. All went well so far until I came to the point where "bids" won't work.

The error that shows up reads "No route passed" once I clicked on "add to bid".

This is an error Log from the console:
