Lottie video resolution changes (original video 1920x1080) gets reduced in size

The composition i have in After effects is made out of PNG images imported as a sequence to AF.

the resolution in AF is full HD 1920 x 1080 but when i export via bodymovin and load it in webflow it trims the video size which leaves these two blank spaces at the sides of the video.
im not sure what im doing wrong here and why this is happening.
Anyone has a solution or encountered it before?

I also tried just rendering the image sequence as a regular video and then using bodymovin to export the Js file but it doesnt seem to be working well.
It seems like the exported file (from video) is empty (original video file is 5mb and the Json file is 480kb.
