AutoCast Problem with AutoCast error code?

Hello everyone, I am quite new to tasker and I love this program.
I try now AutoCast and I don't know why, it doesn't work.

%err
Error Code
Only available if you select Continue Task
After Error and the action ends in error

%errmsg
Error Message
Only available if you select Continue Task
After Error and the action ends in error

I just tried the tutorial "Local media casting".
I just did the first part and have this error.
On my screen there this message: " Error Loading media from httxxxxxxxxxxxxxxxxxxxx The media playback was aborted due to corruption problem or because the media used features your browser did not support. "

I have a Huawei P10 lite.

Someone can help me?

Thank you guys.

 

Ok finally it works. I am sorry. I think the file format did not work.

 

I am getting this too. Only seems to be for certain files (all the same file type). I have an autocast set up to read all my mp4 video files and cast them. It's annoying because the file casts fine from other apps and autocast stoe on the first error. Not sure if you can set autocast to continue after errors?
