404 responses for /users/{userId}/accounts/{accountId}/number

Question

For a new Banno/JH customer of our digital banking plugin, we retrieve the user's accounts, and for each one, make a call to /users/{userId}/accounts/{accountId}/number to get the full account number. We have successfully tested this flow with a different customer.

For the customer in question, two of their users have tested it so far and we're seeing the same issue - while the call to get the accounts for the user succeeds, when we make the subsequent call to the account number API for each account, for some of them we get a 404 response.

A couple representative URLs that return a 404 are:

• https://{customer URL}/a/consumer/api/v0/users/6d7f3421-8a93-4f99-8a5b-a1ee158b890d/accounts/47d4abdd-bbdb-408f-803a-00784affaadb/number
• https://{customer URL}/a/consumer/api/v0/users/6d7f3421-8a93-4f99-8a5b-a1ee158b890d/accounts/7ed6f414-29e0-40f1-823f-f695420eeeb6/number

A couple clues that may or may not be relevant:

• the accountStatus is "Unknown" for both of the above
• the masked account numbers that are returned in the initial accounts data have a non-numeric character in it (x50S0153, x50S0000)

In case it helps, the institution ID is 04b3ba00-413b-4e5d-85bd-12176cf9d664

Appreciate the attention and time to help us with this!
