Not sure if this is helpful. Here's my situation and the way I fixed it. I'm running Safari 12.1

//I created a Blob from data, and appended that blob to more data which mostly failed with "WebKitBlobResource error 1"

const blob1 = new Blob([1,2,3],{type: "octet/stream"});
const finalBlob = new Blob([blob1,[4,5,6]],{type: "octet/stream"});
window.URL.createObjectURL(finalBlob); // fails 8/10 times on Safari

//To fix it I first gathered the data arrays and created a single Blob instead

const data = [[1,2,3],[4,5,6]]
const finalBlob = new Blob(data,{type: "octet/stream"});
window.URL.createObjectURL(finalBlob); // works always
