The error is rather self explanatory, 'Expected hexadecimal character' yet something else is passed.

As it's part of big context this more application specific and you need to find out from which higher level the value is passed. Maybe try the Symfony Slack instead, and provide a complete stack trace (which you can find in the profiler, given this is not in a production env).
