Data Table Node not able to find Data Table suddenly

Questions
1

I’m hosting n8n in Binary Lane with Cloudflare. It’s been working well up until last night. Suddenly, nodes can’t find the data table. Replacing the node hasn’t fixed it, if I recreate a new workflow - it works for a short time and then forgets it again. =(

Describe the problem/error/question

What is the error message (if any)?

Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

I have exactly the same issue.

When I create a new workflow, I can see all the data tables, select the columns, .. everything works fine. Then when I leave the workflow, go to the overview and click back into the workflow, I can;t access them anymore. I see one random data table, even from another project.

the workflow still works though, but If I would want to edit something related to the datatable I need to create a new workflow.

I tried updating docker, restarting, clearing cache, rebooting the server, another browser, .. nothing works (excpect creating a new workflow but then it fails after closing it)

I run the lastest n8n version: 1.123.5
Database: PostgreSQL
Execution process: queue (with autoscaler)
Running via Docker
Operation system: Ubuntu 24.04.3 LTS (GNU/Linux 6.8.0-88-generic x86_64)

Found this later: [Bug] Data Tables node does not detect projectId and existing tables (Self Hosted) · Issue #20399 · n8n-io/n8n · GitHub

Where is says that if you go to your workflow via the “Personal” menu/tab you can see the data tables correctly. I can confirm this works for me.

I hope this helps @_Niki
