    uploadFeature({
        provider: {
            aws: {
                accessKeyId: process.env.AKN7H,
                secretAccessKey: process.env.S3_SECRET_ACCESS_KEY,

        },
        properties: {
            key: "fileUrl", // to this db field feature will safe S3 key,
            mimeType: "mimeType", // this property is important because allows to have previews,
        },
        validation: {
            mimeTypes: "application/pdf",
        },
    }),
],
};

Answer 1

 validation: {
        mimeTypes: "application/pdf",
    },

'mimeTypes' + for array : mimeTypes: ["application/pdf"]

'mimeType' + for string : mimeTypes: "application/pdf"
