Bug: Unable to recognize the file type

I’m able to successfully process the image with postman, but when I try to send the same image in my android app I keep getting this error:
{“OCRExitCode”:99,“IsErroredOnProcessing”:true,“ErrorMessage”:[“Unable to recognize the file type”],“ProcessingTimeInMilliseconds”:“0”}

I’ve been at it all day and can’t figure out why I’m getting this result.

Here’s my kotlin code if anyone can give insight:

    image.compress(Bitmap.CompressFormat.JPEG, 100, baos)
    val bytes = baos.toByteArray()
    val encoder = Base64.getEncoder()
    val body = "data:image/jpeg;base64," + encoder.encodeToString(bytes)
    val queue = Volley.newRequestQueue(this)
    val url = "https://api.ocr.space/parse/image"
    val jsonObjectRequest = object: JsonObjectRequest(Request.Method.POST, url, null,
        Listener<JSONObject> {
        }, Response.ErrorListener {
    ) {
        override fun getHeaders(): Map<String, String> {
            var params = HashMap<String, String>()
            params["Content-Type"] = "multipart/form-data"
            params["apikey"] = "xxx"
            return params

        override fun getParams(): MutableMap<String, String> {
            var params = HashMap<String, String>()
            params.put("language", "eng")
            params.put("scale", "true")
            params.put("istable", "true")
            params.put("ocrengine", "2")
            params.put("detectorientation", "true")
            params.put("base64Image", body)
            return params
