Unsupported Buffer file-type

[uberiain]

Hi, I have a problem sending a video buffer from frigate to telegram. It gives me the following error:

Caught exception in sender node:
Error: SLIGHTLYBETTEREFATAL: Unsupported Buffer file-type
when processing message:

What could be the reason?

Thanks

@uberiain how do you send the video? Do you have an example flow?
In what format is the video?
https://core.telegram.org/bots/api#sendvideo says that the video must be MPEG4 and it must not be longer than 50MB

This is my example flow used to send the video:

@uberiain please send me an example file via email (see my profile)

The file type could not be determined by the internal logic: pass the content type as follows

`
msg.payload = {
type: 'video',
content: msg.payload,
chatId: ...,
fileOptions : {
contentType: 'video/mp4'
}
}

return [msg];
`
