Troubleshooting and FAQs

Frequently asked questions and troubleshooting advice for our Plaid integration

"Connectivity not supported" error when trying to connect a bank account​

If you receive the "Connectivity not supported" error message when trying to connect a bank account via Plaid, it is likely because of one of these reasons:

  • The institution does not support one of the products specified in Link initialization.
  • The institution is associated with a country not specified in Link initialization.
  • The institution is associated with a country your Plaid account hasn't been enabled for.

In practice this means that the selected Plaid institution does not support Instant Auth as an authentication method. Fortunately, there is an alternative to Instant Auth called Instant Match, which Codat uses as an authentification fallback.

Banking transactions fetch error on first sync​

You may very occasionally notice fetch errors on your first attempt to sync banking transactions for companies linked to the Plaid integration with subsequent attempts completing without issue.

When fetching transaction data from Plaid, we make an outbound call to their API to initiate a background job that collates the requested data. Once the job is complete, Plaid sends the results to Codat via a webhook. Sometimes the data preparation can take more than 15 minutes, which will trigger a timeout on our side. As a result, we will return an error for the operation. This happens when a particularly large volume of data is involved, for example, during the first sync.

The subsequent requests to fetch this data will succeed because the initial job would have already progressed from the earlier request. This often happens shortly afterwards. Simply initiate another sync for the data type to resolve the issue.

"Action required with your account" error when connecting a bank account​

This error is likely because the user authorizing the connection doesn't have the correct permissions assigned to their user account within the bank platform. The steps to resolve this vary from bank to bank, but most banks provide detailed resolution instructions in their own documentation. For example, see Chase's own resolution tips.
