use the codeceptJS v1.4.4 and that’s it.

[LucasBrazi06]

@LucasBrazi06 You are confusing codeceptjs (latest is v1.4.4) with puppeteer (latest is v1.9.0). upgrade your codeceptJS to v1.4.4 and try to see if it fixes your problem.

Sorry for the confusion! I just upgraded to codeceptjs 1.4.4 and it works fine. Thanks for your support!
