Error: "An unexpected error occurred"

The same error might also say "timeout executing POST".

The cause:

If you've been exporting from Pleo to Xero for some time, you might see the message "An unexpected error occurred." There is a limit of "interactions" that can happen between Pleo and Xero before the integration needs to be refreshed.

The solution:

Please disconnect and reconnect the Xero integration.
