I just updated my app. Now I get the following error in the log:
parse error: Invalid string: control characters from U+0000 through U+001F must be escaped at line 38, column 3
That’s it. Would be good to know which file is involved here.
Our error logging does try to identify file name and links you to the file and error line in the source. If you let us know your project name, I can look into why this isn’t happening in this case.
Found the problem in the meantime. The problem was in the package.json file.
The project name is iwamiguide.
