Warning messages

Hi all,
I’m having these warnings message but I can’t find the reason why.

Any idea of where are they coming from?

Thanks in advance.

They are fine to ignore, currently our server is using the mimetype to serve certain text files.

The deprecated warning though means that you are using an old API that we may remove in the future. Ideally, you should update it to use our current API.

Ok, thanks for the answer.
