When queried, the /transactions endpoint (https://telesto.api.barclays/open-banking/v3.1/aisp/accounts/AcountID/transactions) returns a Next link to /balances (https://telesto.api.barclays/open-banking/v3.1/aisp/accounts/AcountID/balances...) rather than the next available page of transactions. This then returns a 500 error:
"Message": "Unexpected Error occurred while processing the request "
For additional context (if helpful) - after an automated retry attempt at hitting the erroneous Next / balances endpoint we then received a 400 auth issue:
"Message": "Consent validation failed because of invalid data. "
Unable to obtain transaction data beyond first page of results
Transaction data is critical to our business use-case
