Hello,

I use Sendbird Unity SDK to send messages and files(images, videos) in my chat. I would like to send the file with FileMessageParms because I want to set thumbnails for the images and videos. But I can’t send the file with FileMessageParms. I set all properties and the “Invalid Arguments” exception is happening.

Thank you so much  
Thiha.
