I am spending like 4 hours to remove this error no - (1). There is no error actually. I can run debug mode with this error indication. And I download the source code and it's running on locally. I have 3 team members and all of them has no error indication. It appears on my end only. I have tried many things repeatedly like closing browser and signing again, changing web browser, etc. Wish it gives a hint how I could get rid of it. <img width="594" alt="image" src="https://user-images.githubusercontent.com/5080329/208357950-7642b532-44e2-41ff-9956-cb63e93d2c14.png"> --- After the struggling of 12 hours yesterday, and 6 hours today, ... I suddenly thought, It all happened with recent update.... and what I did on recent update? Supabase. I removed Supabase and the error `Custom Code error (1)` has gone now !! But I see different error. --- After hours of struggling, we found that it's really Supabase that's causing the problem (in our case). We have tested on many projects and found that every time we work with Supabase, the problem appears. I have a video recording to re-produce the error and fix the error. We finally fixed and able to run the project after removing Supabase. See the video below. ** How to Reproduce ** 1. Add a custom action. 2. Set up Supabase. 3. Edit the custom action. And you will see the `unknown error` or `custom action error`... ** How to Fix ** - To remove the Unknown error, simply disabling Supabase will NOT solve the problem. 1. Go to settings -> Supabase 2. Clear Schema 3. Disable Supabase 4. Compile again. https://user-images.githubusercontent.com/5080329/208668021-6a908276-19a9-467b-a45e-32e1ec889e23.mp4
