I have a simple issue, but it's been driving me crazy for the past 2 days.
I have an archive.zip file in my node/express app which I'm trying to send via a response.
My code is pretty simple, I have an endpoint /download whos only job is to do response.download("archive.zip").
However, upon downloading the file (by accessing the URL through a browser), the .zip archive is downloaded, but the files in the archive are corrupted, and I get the error Unexpected end of archive.
The actual file is a good, non-corrupted archive. I can access it on the windows filesystem without any problems. It's just when it gets transferred it gets corrupted.
I have tried setting various response headers, among which:
Content-Disposition: attachment
Content-Type: application/zip, application/content-stream
Transfer-Encoding: chunked
Nothing has worked up to this point. I have searched far and wide on google / reddit / stackoverflow and haven't come up with a solution so far.
Thank you for any or all responses.
NOTE: I'm using Express Router (require('express').Router())
NOTE2: The simple zip I'm trying to download - http://s000.tinyupload.com/?file_id=06192736420392118369
The problem came from bad async patterns and chaining. The operations were not executing in the correct order, thus my archive was being sent before it was finalized.
