App service returning bad gateway

Hi Alex,

Thanks for you response.

It does seem like the issue is related to the file size in form-data. I tried uploading a lower size file and it went through. I am uploading a 5mb file that seems to be causing the issue.

What do you think where should i update the required stuff. I have a docker image on ubuntu. I am using gin with Go.

Thanks

I have fixed it by reading and discarding the multipart form data. That way azure doesn't raise any concern for the request :-)

func discardMultipartDataIfAny(context *gin.Context) {
	data, err := context.Request.MultipartReader()
	if err == nil {
		for {
			part, err := data.NextPart()
			if err != nil || err == io.EOF {
				break
			}
			_, err = io.Copy(io.Discard, part)
			part.Close()
			if err != nil {
				break
			}
		}
	}
}
