I have an app that uses the Privacy API to anonymise user details upon request. The app generates a JWT and sends it to https://ims-na1.adobelogin.com/ims/exchange/jwt to retrieve an access token to use for the Privacy API request. However, following the recent changes to the Adobe I/O console, my app has stopped working. In an effort to get it working again, I have created a new project in the console to use for it. Now when trying to get an access token, I am getting a 400 bad request error with the detail of "Could not match JWT signature to any of the bindings". Can anyone please tell me exactly what causes this specific error? I can't find it mentioned in the documentation.
