Is there any more information associated with this error, like the entire stack trace, that you could share in this issue? I am not sure how to reproduce the issue currently.

and the stack trace from browser:

[user1736]

Ok, an update here: removing node_modules and installing it again helped me

[user1736]

any news here? even though removing node_modules helps it's still awkward to do it regularly

[malyborky]

For me removing node_modules didn't help

[jesperorb]

What version are you on @malyborky and @user1736?

@debabrata100 I see that you are using 0.13.7, have you tried upgrading to v1 och v2?

[user1736]

@jesperorb it's 1.2.0

[timsully]

Any update on this issue?

[rakannimer]

Any chance you can update to v2 ? Happy to help if you encounter issues when updating.
