Missing Content-Type about busboy HOT 7 OPEN

It's not a case-sensitivity issue with content-type. The problem seems to be that the cfg.headers['content-type'] statement returns undefined because the headers in the routing endpoint's request are not a plain map.
This is because busboy is not getting the value in the form of headers.get('content-type'), but using index brackets. To make it more convenient, it seems like a good idea to ask busboy authors to use headers.get.

In a nutshell, try this:

    const simpleHeaders = {};
    for (const key of request.headers.keys()) {
        simpleHeaders[key] = request.headers.get(key);
    }

    const busboy = Busboy({ headers: simpleHeaders });

or

    const busboy = Busboy({ headers: Object.fromEntries(request.headers) });

Have you checked the contents of event.headers to know what is the proper casing? It must be something other than the two you're attempting to access.

@mscdex I logged it. It is lower case

from busboy.

headers: {
        ...event.headers,
        "Content-Type":
          event.headers["Content-Type"] || event.headers["content-type"],
      }```
      
      I tried updating the string here to have to exactly same case the error is mentioning.

I don't know what to tell you then as event.headers seems to already have only lowercased header names. The only way you can get the "Missing Content-Type" error is if the headers object you pass to busboy is a non-object, null, or if headers['content-type'] is not a string.

Just to double check, what does typeof event.headers['content-type'] show?

from busboy.

It logs back as string

I really feel there might be something on Busboy's end that is messing this up. I think people still have these problems with lamda functions - saw that when I was going through all the issues here

Well, you'll need to dig into the code and troubleshoot it yourself then because I have no explanation as to why you're receiving that particular error in this case.
