Cannot add Monzo for barclaycard Direct Debit

I’ve tried to change my Direct Debit from Lloyds to Monzo for my Barclaycard, however, when I enter all my details I get an error code on the Barclaycard app BDDE3 and it says to check the details again. It won’t let me set this up.

Any ideas on how to make this work?
