App crashes on changing .pegjs file

Hello,

I am working on an issue that requires modifying the grammar.pegjs file. Can I make changes to this file? If yes, why does the application crash when I apply valid changes?

I have said before - ask your properly documented question.

What you have told us doesn’t actually tell us anything much.

After looking various files I come to grammar.pegjs file which is used as message parser when I am making changes which are valid the app crashes giving:

the Question here is can i make changes in grammar.pegjs file? if yes, then why the app is crashing?

Making syntactically changes to any file should work.

So either your syntax is wrong, or something else with your test setup is broken.

First thing to ALWAYS check. Logs.

What do they say?
