docx file gets corrupted while downloading from backend server

I've got a request from VueJS frontend to my backend server:

let config = {header : {'Content-Type' : 'multipart/form-data'}};
const res = await axios.patch(`http://0.0.0.0:8080/report/${this.docGuid}`, data, config);

Response headers:

HTTP/1.1 200 OK
date: Tue, 30 Mar 2021 13:05:00 GMT
server: uvicorn
content-type: application/vnd.openxmlformats-officedocument.wordprocessingml.document
content-disposition: attachment; filename*=utf-8''IL-NS-0_LSM.docx
content-length: 600357
last-modified: Tue, 30 Mar 2021 13:05:01 GMT
etag: c1a4f72bf0ad07234099ac6cec97e635

Request headers:

PATCH /report/cb07f12a7a49435e8e0f306e71c01969 HTTP/1.1
Host: 0.0.0.0:8080
User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0

Connection: keep-alive

which is creating a MS docx file on server side and reverted this created file in response. I try to download it:

let blob = new Blob([res.data], {type: res.headers["content-type"]});
window.open(URL.createObjectURL(blob));

And it works, except dowloaded file is corrupted and I cannot open it. Besides serverside copy is fine and openable. MIME type set as "application/vnd.openxmlformats-officedocument.wordprocessingml.document"

What could be wrong? Thanks in advance)

I finally found out that there should be responseType parametr set as blob. So:

config = {header : {'Content-Type' : 'multipart/form-data'}, responseType: 'blob'};
