Just closing the loop on the thread; the issue was resolved in a spread thread with the following solution:

> All of your requests to Finicity look good; however, when generating partner consent, it looks like `thirdPartyPartnerId` is currently set to `2445583094600`. This value should instead be Dwolla’s Finicity partner ID, which can be found [on this line](https://github.com/Dwolla/integration-examples/blob/main/packages/finicity-token-exchange/src/integrations/finicity.ts#L25). In other words, can you attempt to recreate the partner consent using Dwolla’s ID, similar to the following snippet?
