Supabase node connection issue #20891
Description
Describe the problem/error/question
I have several workflows that connect to Supabase (select, create, etc.).
Until October 13, I was using the free version of Supabase. But it turned out to be insufficient (I exceeded the disk quota).
So I switched to the pro version.
Since then, the flows have been working, but I have a number of them that are failing.
Based on my observations, and without understanding why, the errors start occurring at 2 p.m. French time. Several hundred errors are then raised. But not all flows are in error, sometimes 10%, sometimes 90%.
When I look at the node in question (whether it's a select, create, update... it's the same thing), the error is always ETIMEDOUT.
I contacted Supabase support, who told me that my Supabase instance is not receiving any API calls.
I have some flows where a Select node is followed by an Update. Sometimes the error occurs on the select, sometimes on the update.
I don't see any logic in the errors.
I contacted Supabase support, who told me: “The errors you have provided do not show any Supabase-related error.”
However, the coincidence is troubling. The errors started on the same day that I switched to the pro plan.
What is the error message (if any)?
Supabase nodes indicate connect ETIMEDOUT [IP]:443
Another issue is that when I open a Supabase node, the list of tables and fields takes a long time to refresh.
Please share your workflow/screenshots/recording
This is a test workflow where I am simply performing a select operation on a Supabase table. I am encountering the same errors (but not consistently).
