I am having an issue uploading files to my server on a frontend rewrite I am working on.
I am getting an error response 500 "Premature end of script headers:" I have my headers recreated almost exactly the same as the legacy web app I am trying to recreate with two exceptions.
Backstory: I am recreating a Flash web application in Vue.js. I am using the exact same back end intact, it is Perl, cgi scripts, generally, I am able to use axios to talk to the backend scripts no problem.
Current Flash Frontend: When I upload a file with the current flash app my header looks like this.
Note the highlighted text at the bottom.
Replacement Vue Frontend: I see a couple differences with my new header, I don't have the Content-Type: application/octet-stream bit directly underneath the filedata part of the header. And the end of the header is "--" which is the convention, I am guessing the old application used some outdated header ending I can't find and doesn't know how to handle mine. Please help I could not find anything on the Google. I also note the new header has "WebKitFormBoundarys" not sure if that could cause an issue with some old header standards or something.
Issues were related to outdated Perl packages, once they were upgraded to backend script recognized the header correctly.
