How to fix the fetch Missing boundary in multipart/form-data POST error with JavaScript?
To fix the fetch Missing boundary in multipart/form-data POST error with JavaScript, we set the Accept request header to "*/*" to accept all response MIME types.
For instance, we write
const options = {
//...
headers: new HttpHeaders({
Accept: "*/*",
Authorization:
"Bearer " + JSON.parse(sessionStorage.getItem("token")).token,
"Access-Control-Allow-Origin": this.apiURL,
"Access-Control-Allow-Methods": "GET, POST, OPTIONS, PUT, PATCH, DELETE",
"Access-Control-Allow-Headers":
"origin,X-Requested-With,content-type,accept",
"Access-Control-Allow-Credentials": "true",
}),
//...
};
await fetch(url, options);
to create a HttpHeaders object with the Accept header set to "*/*" to set "*/*" as the Accept request header value.
Then we call fetch with the options object to make a request to the url with all the request headers listed.
Conclusion
To fix the fetch Missing boundary in multipart/form-data POST error with JavaScript, we set the Accept request header to "*/*" to accept all response MIME types.
