Error: "pairedItem can't be found" in workflows with WhatsApp nodes after n8n upgrade

Questions

Hi,

Since upgrading my n8n instance, all my workflows that include WhatsApp nodes are failing with the same error. The issue seems to occur consistently across multiple workflows, and I’d really appreciate any insights or suggestions from the community!

Here is the error (Cause detailed:
pairedItem can’t be found when intermediate nodes between ‘Get Text‘ and ‘WhatsApp Business Cloud15’ have not executed yet.
Stack trace:
ExpressionError: Can’t get data for expression).

I have checked the nodes before and after where it fails but non shows errors in the development mode.

I have even rolled back on railway.com to see if the problem goes away but is still persisting.

Has there been a change in the latest n8n version that affects how expressions are evaluated or how execution order is managed, which could explain this error?

How can we fix this, am I the only one to report this after the upgrade?

I need urgent help and thanks in advance for any help or pointers you can provide!

Regards,
Viljoenco

Yes I had this problem immediately. All my WhatsApp send nodes now fail since update.

Great news, how long do you think it will take? Promised my manager the earth moon and stars.

Just roll back to 1.81.4 until it’s fixed.
