I had this issue since morning and got in contact with the dwolla team. They claim that when they ping plaid api they are getting errors and thus are causing us to get errors. as of right now there is nothing you can do. I wrote my code in correspondence to plaid+dwolla through every guide. The code worked seamlessly for months and as I was about to release a change this error appeared.
For now you are just going to have to wait until this resolve this. through my chats with them they contacted plaid already.
Partial Correspondence with Dwolla:
{ Error: {“code”:“ValidationError”,“message”:“Validation error(s) present. See embedded errors list for more details.”,"_embedded":{“errors”:[{“code”:“Invalid”,“message”:“Token is invalid.”,“path”:"/plaidToken","_links":{}}]}}
Hi Victor, Is this error only occurring in the Sandbox environment?

We currently have a message out to the Plaid team to figure out what the issue is with the token exchange endpoint in Sandbox. We are receiving an exception from their API when making requests.
