Incorrect MIME type in storage.createFile

I’m facing an issue with storage.createFile.

I’m trying to upload a .css file and I’ve explicitly set the MIME type to "text/css" when creating the file. But after uploading, the file in Appwrite storage still shows up with MIME type "text/plain".

Here’s what I’ve checked:

The file has the correct .css extension.

I passed "text/css" as the MIME type.

The file uploads successfully, but the type is still wrong.

Any ideas why this is happening or how to ensure the correct MIME type is stored?
