Barclays - V3 invalid transaction Next link

[lucas-s-work]

In this situation when attempting to fetch transactions from multiple accounts the Next transaction link is invalid with missing account_id and incorrect path.

Expected

"Next":\"https://telesto.api.barclays/open-banking/v3.1/aisp/accounts/--account_id--/transactions?toBookingDateTime=--to-time--&offset=50&fromBookingDateTime=--from-time--0&limit=50&includePendingRecords=false

Received

"Next\":\"https://telesto.api.barclays/open-banking/v3.1/aisp/accounts?toBookingDateTime=--to-time--&offset=100&fromBookingDateTime=--from-time--&limit=50&includePendingRecords=false\

Impact

High, this prevents use of transaction data as it may be incomplete.

Further to the previous issue related to pagination, we've encountered the following with the Barclays v3 endpoint today.

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 returns a 500 error:

{
      "ErrorCode": "UK.OBIE.UnexpectedError",
      "Message": "Unexpected Error occurred while processing the request "
}

For additional context - after an automated retry attempt at hitting the erroneous Next / balances endpoint we then received a 400 auth issue:

{
  "ErrorCode": "UK.OBIE.Field.Unexpected",
  "Message": "Consent validation failed because of invalid data. "
}
