400 bad request with media and media_with_thumbnail methods

[ckruse]

Hi there,

when trying to upload a picture with the media request I get a 400 bad request response. Doesn't matter if I post to my local test installation or an publicly available Mastodon instance.

Creating a status w/o medium works.

This is my code:

    let toml_path = env::var("MASTODON_TOML").expect("env variable MASTODON_TOML not set");
    let mastodon = Mastodon::from(toml::from_file(toml_path).unwrap());

    let path = format!(
        "{}/{}/original/{}",
        image_base_path(),
        picture.id,
        picture.image_file_name
    );

    let thumbnail_path = format!(
        "{}/{}/thumbnail/{}",
        image_base_path(),
        picture.id,
        picture.image_file_name
    );

    let attachment = mastodon
        .media_with_thumbnail(path, thumbnail_path, picture.alt.clone())
        .await
        .map_err(|e| {
            println!("Error uploading media: {}", e);
            e
        })?;

That produces this error message:

Error uploading media: Api { status: 400, response: ApiError { error: "Bad Request", error_description: None } }

Am I doing something wrong or is this a bug in the library?

Best regards,
CK

Confirmed, this also happens with the upload_photo example. Investigating.

I saw this corresponding log in my server:

I think I know how to fix this, if I'm right I'll have a patch in a little while
