That’s weird. Haven’t seen this myself ever.
Simple workaround would be to create a new server action. It could be that your file is corrupted somehow.
- Open the current file in editor - right click and “open in editor”.
- Copy the JSON.
- Create a new server action - preferably with some other name.
- Open the new server action in editor.
- Paste the JSON as save.
- Try to open the server action in Wappler UI and modify… see if it works.
Also, maybe try to add a new step or something too, to test. It could be that the DB query step itself is misconfigured somehow.
