New Think Tool Problem ("Unrecognized node type")
Hello everyone. I have just tried to integrate the new Think tool into one of my existing workflows to improve the quality of the AI Agent results. This workflow is a sub-workflow that is triggered by a parent workflow. The latter now immediately runs into an error and the node (Execute Sub-workflow) reports: Unrecognized node type: @n8n/n8n-nodes-langchain.toolThink Does anyone have an idea what the problem is? My N8N Version is 1.88.0 Thank you!

@Valentin Ffrench Hi Valentin. Thanks for your response. I was able to reproduce the error in a very simple workflow. used a simple “trigger workflow” (Scheduled Trigger) and the main workflow with the new Think node. When I execute the workflows manually, everything works perfectly, even in the context with the Think node. However, as soon as I switch the workflows to “active”, the errors are always generated. Note: I already had a similar problem related to Postgres nodes after an N8N version upgrade. In the end, the solution was to downgrade the version of the Postgres node (from 2.6 to 2.5).

Issue with Postgres Nodes in n8n (Railway)
Hi everyone, I have a problem with my n8n installation on Railway. The mere presence of Postgres nodes in a workflow (even if they are disabled) prevents the workflow from running automatically (e.g. by a schedule trigger). An error is reported in the Executions. If the workflow is executed manually, there are no problems and the Postgres nodes also work properly. Does anyone have any idea what could be causing this?

Thanks @Norbert Walczak ! Looks like the problem is solved. How do you handle the creation of new workflows with Postgres? By copying existing nodes of version 2.4?
