Recently in one of our custom pages, we were getting the below error
“Invalid data from the network”
We had this setting “Formula-level error management” as On, switching it off was hiding this error on the page.
To fix it we tried removing the fields one by one to figure out the issue. Eventually, we saw the error was going away if we remove one of the option set fields from the gallery or comment it’s formula. Later when we removed and added the field back in the gallery and the error got fixed for us.
The page loading properly without the error –
Hope it helps..
