I tried to follow your stemp to show a large video in WeDev Module, I segmented the video to small chunk around 6MB and created both playlist.m3u8 and master.m3u8, and importing every file into the WebDev module using Content-Type video/mp2t and application/x-mpegURL respectively for .ts and .m3u8 file, I also tried to recreate the URL like said here Playing a video using WebDev - #10 by Zach_Larson also trying to add and removing "" and {session.props.gateway.address}, but still every time that I use the mounted path of the master or playlist file into the video component I get error as "File Not Supported"
