Without taiko-screencats, the script runs successful. Here's the demo.js.txt

hi, thanks for reporting this. I am unable to run your script since it seems to be using an internal URL/credentials.

The stacktrace suggests that for some reason taiko-screencast prevents the removeListener to be fired. This is strange.

Would it be possible for you to share a script that hits a public url?

Also, please share what version of taiko you are using.

[varac]

Also, please share what version of taiko you are using.

I'm using 1.2.5 (Chromium: 88.0.4314.0) RELEASE and latest taiko-screencast.
I'll send you credentials for a test server since there's no public url for the components I'm testing.

have same problem with 1.2.5

[sriv]

This was a problem with taiko-screencast rather than taiko itself. I've made some changes and v0.0.2 is out. Can you please try with [email protected] and see if the problem still exists @dvag-michael-boiman ?

thanks

[ghost]

wow thanks, this was fast. I will try it today and give u feedback

[ghost]

I tryed it with gauge + taiko 1.2.7 and screencasts 0.0.2
Now the problem if u have more than one scenario (only one need to have screencast capturing) the task not ending.
I See the log that the gif was saved, but it is not ending. maybe I try to stop the screencast without the await?
await screencast.stopScreencast(); --> screencast.stopScreencast();
or is there a possibility to kill the process with something like screencast = null; ?

[sriv]

I need to verify this, but the API should be as before, i.e. await screencast.stopScreencast() should terminate the screencast.

[ghost]

i don't see nothing in the log of gauge & taiko, if u have an idea where I can find more logs let me know

[ghost]

I go back to 0.0.1 running worser than before.
