## TL;DR

For "dwollav2.error.Error: {"code":"UpdateCredentials","message":"The login details for this token have changed."}": upgrade dwollav2 to a release containing the new class and catch it by name instead of parsing the generic Error message.

```text
dwollav2.error.Error: {"code":"UpdateCredentials","message":"The login details for this token have changed."}
```

## Steps

1. Creating a funding source via Dwolla/Plaid tokenization with an expired token
raised a generic error:

```
dwollav2.error.Error: {"code":"UpdateCredentials","message":"The login details for this token have changed."}
```

2. The generic `Error` class made it hard to isolate expired-token cases from other
failures.

3. The Dwolla team agreed and shipped a dedicated error class specifically for the
`UpdateCredentials` scenario (resolved by PR #58). Upgrade dwollav2 to a release
containing the new class and catch it by name instead of parsing the generic
`Error` message.

## When to use

You are seeing this: They deliberately did not make it Plaid-specific: the same code is sent for any third-party open-banking verification provider, so the error class covers all of them. Use this skill when you run into "Dwolla dwollav2: catching expired Plaid token errors (UpdateCredentials)".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
