Agent Tool supports model v2.2 while Agent node requires v3 – version mismatch on n8n v1.123.5

Running n8n v1.123.5 self-hosted and hitting a mismatch between Agent node (v3 models) and Agent Tools (v2.2 models).

Error:

This model is not supported in 2.2 version of the Agent node

Is this a known limitation of v1.123.5, or is there any workaround without upgrading to v2?

This version mismatch is a known limitation in n8n v1.123.5. The Agent node was updated to support v3 models while Agent Tools remained on v2.2. Unfortunately, there’s no workaround without upgrading to n8n v2.x, as this requires core changes to align both components. You might want to consider upgrading to the latest version to resolve this compatibility issue.
