I'm having issues with WAB now because I accidentally deleted a portion of the text from the Server/DB/apps file. I did make a text copy of it stored in another notepad and when I tried pasting it back and relaunching WAB, it gave me a syntax error (unexpected end of input). I tried very hard to look for mistakes in the code by making sure that the code has the appropriate parenthesis but being unfamiliar with the language used, that is all I could check for. It is really strange since it is the exact same information unless there are hidden characters/hashes that I can't see.
Now, I'm stuck with a broken WAB and I don't really want to recreate the apps from zip because some the apps were created from a different AGOL account and by different users. I don't know if there is a way to recover this information.
Any help is much appreciated !
