Syntax Error at "sub" missing ";" in Feature dlig

There is a Syntax Error while updating (or exporting) my dlig’s. But: I can’t see the error.
There is no missing “,” in line 46.

The line numbers are sometimes not really accurate. Look in the lines before or after. If you can’t find any problem, Maybe you have some not printing characters in your feature code.
If that does not is the case, try to generate the font from the temp folder: glyphsapp.com/tutorials/troubleshooting-a-font-that-does-not-export
