Sellers cannot accept payments due to a "temporary bug"

Whenever I run a workflow to Transfer funds to a Seller in my marketplace I instantly get an error message as follows.

I’m using test data and I’ve tried everything I can think of including:

  1. Simply enter the amount being transferred as ‘550’ so that it doesn’t look up the figure anywhere in my data. Doesn’t make any difference.
  2. Ensured that the redirect URL in Stripe is correct…makes no difference.

  1. Called Stripe who confirmed that all my sellers are set up correctly.

Can anyone advise me on this? It’s been appearing for over a week so any assistance would be much appreciated.
