Youtube API v3 : order = date is not working

I'm junior developer.

I'm using youtube api v3 in mini project.

We are currently working on retrieving the three most recent video contents from a specific channel through the YouTube API, saving them in the database, and displaying them on the view.

However, since the last few days, I have been receiving responses in a mixed order(not published time desc) rather than the three most recent videos.

Request Url :https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=[specific channel]&type=video&order=date&key=[my key]

Is there anyone experiencing a similar type of problem as me?

I changed the request url parameter sequence.

but it always returns same result (mixed result)
