What happened?

I have a financial institution for which SimpleFIN sync does not work via Actual Budget.

Actual Budget Version 25.1.2
Running via Docker on Synology NAS - DSM 7.2.2-72806 Update 3
Mozilla Firefox 135.0 (64-bit)
Google Chrome 133.0.6943.99 (Official Build) (64-bit)
Microsoft Edge Version 133.0.3065.59 (Official build) (64-bit)

When I attempt to sync an account from this bank, I receive the following error at the top left of the UI in a red box, above the account name:

This account is experiencing connection problems. Let's fix it.
The server returned the following error:
An internal error occurred. Try to log in again, or get in touch for support.

With the option to unlink the account.

At the bottom right of the screen, I receive this pop-up in a red popup box:

Failed syncing account "[BANK] [ACCOUNT]"

These are the logs captured form the server side:

2024-11-15 - 2025-03-01
The account "ACT-1f2ea2f7-55de-4bf3-a526-ae43488c08a5" was not found. Here were the accounts returned:
2025-02-13T22:08:34.005Z info: POST 200 /simplefin/transactions
2025-02-13T22:08:34.063Z info: POST 200 /sync/syn

These logs are form the Developer Console in Mozilla Firefox:

This bank works properly through SimpleFIN if I use their example Python code. I get all accounts returned from this bank, and I get all transactions via the example Python code. This does not seem to be an issue with SimpleFIN.

Additionally, if I review the Account Links to SimpleFIN, there is no online account listed for the accounts from this bank.

How can we reproduce the issue?

Attempt to sync the account.

What browsers are you seeing the problem on?

Firefox, Chrome, Microsoft Edge
