.mp4 videos are not sent as .mp4 can anyone please help me

[nishant-aka-nik]

After uploading the .mp4 video file from the CLI the video is sent as a non playable .mp4

I want a playable video like below -

Output message -
««« [video: type=video/ size=100x100 duration=100 size=164MiB] test.mp4

I believe the problem is "type=video/ " is sent as empty if it will be like "type=video/mp4" then it will be as playable video
But I am not able to figure it out how to change this can anyone please help me. my side project will be completed if this will be solved
