1.1.0, 1.1.1 - error when starting the pooled timer

[bubenkoff]

Uncaught TypeError: Super expression must either be null or a function

Getting this error in production build only, for some reason

[headzoo]

Is there any kind of stacktrace? Any differences between dev and production, like different operating systems?

[bubenkoff]

as it's a production build, there's not much known unfortunately
it's a browser app, no difference in browsers prod vs dev
do you run the recent version in production with no problem?

[maoryadin]

Same for me, happen only in production.
something related to react-moment.

Operation systems difference:

dev - Windows.
production - Linux.

[maoryadin]

Solved by downgrade to version 0.9.7

@bubenkoff

[bubenkoff]

@maoryadin yes, I also 'solved' it like this

[headzoo]

Are either of you using UglifyJS in your webpack config? Adding keep_fnames: true to your UglifyJS config might fix the problem.

[bubenkoff]

@headzoo yes I do, but keeping ALL the fnames will increase the bundle quite a lot, which function name exactly should be preserved?

[loudbel]

same with reactjs 18.02 , any new solution ?
