# I keep getting this response from the transcriptions endpoint: 
{"error":{"message":"Invalid file format. 
 Supported formats: ['m4a', 'mp3', 'webm', 'mp4', 'mpga', 'wav', 'mpeg']",
 "type":"invalid_request_error","param":null,"code":null}}


# But the blob I'm uploading has type mp4... I think? Here is the blob's console output:

{"_data":{"size":252408,"offset":0,"blobId":"716D0789-6787-4D4B-A60E-72AE30483195","type":"video/mp4",
"name":"recording-734C56FB-EB50-45C1-86CE-027AC71257F4.mp4","__collector":{}}}


# And here is the code where I'm logging both of those things:
const uri = recording.getURI();

    const file = await fetch(uri);
    const blob = await file.blob();
    console.log("Blob type: ", blob.type, "Blob: ", blob);
    const filename = uri.split('/').pop();
