TrueLayer call backs routing to "Unknown Destination" error page.

Incident Report for Codat

Resolved

End-users attempting to link to TrueLayer would've experienced an issue for an approximately 40 min period this morning, where the callbacks to the Codat system, after authenticating on the banking-provider side were failing with an error page which read "Unknown Destination".

Affected users would have noticed that after they entered their credentials in their banking-provider's app, when they would ordinarily get directed back to the Codat system, they would've instead seen an "Unknown Destination" error in their browser.

We have resolved the incident now. End-users will be able to link to TrueLayer successfully and be directed back to Codat's application.
