I keep getting this error. I delted the concetors and re-added them and I removed all the custom cards. But none of these help. The strange thing is, when I close the browser instance and re-run tha app in a new instance, I am able to save the data. However, if I need to save data again, I have to close the second browser instance and re-run the app in a new browser instance.
Does anyone have a solution or suggestion what could be wrong in my app?
