[BUG] Nordigen account disconnects after 1 month

[LucBerge]

Describe the bug
I use the Nordigen source to retrieve transactions on my account. Everything is working fine for 1 month and then I don't receive new transactions. I found out that my Nordigen account disconnects after1 month. I have to reconnect it every month to fix the issue.

To Reproduce
Steps to reproduce the behavior:

1. Create a Nordigen source and connect it correctly
2. Wait 1 month for your Nordigen account to be disconnected

Expected behavior
It should not disconnect.

As I wasn't able to reproduce this, I'll add tracked-internally for Pipedream's Engineer to do the further check 🙏

@LucBerge we have a suspicion that this might be related to how Nordigen is handling authentication, since there are a few unique / off-spec parts of their authentication strategy:

1. They expire their refresh_token after 30 days (this is typically a longer-lived token, unlike access_token)
2. They declare the expiry of the access_token via access_expires instead of the standard, expires_in

We made a change to the app's refresh strategy yesterday that should hopefully handle # 1, and we have a patch in review now that should enable us to handle # 2 (being tracked here)

[LucBerge]

So I guess refreshing the refresh_token every 30 days is the solution ?!
I'll let you know if it works in January, thank you

This should be completed! Please let us know if you see any issues

FYI we just shipped an update to handle Nordigen's custom access_expires field, which should hopefully resolve the issue.

Ok, I'll let you know here
