AWS Lambda - BatchProcess - "cannot reject already-fulfilled task" about exiftool-vendored.js

[SDBurt]

Thanks for the quick reply and the feedback. There are a bunch that I have attempted to use, but this library is much more feature-rich, especially for extracting binary data.

Cheers.

Sorry, this library doesn't support AWS Lambda.

If I had to use that platform, I'd use a library that directly read from the node process (rather than how this library works, which is to spawn an external process to do work). Unfortunately, I couldn't find one that was robust, which is why I wrote this library in the first place. There may be new alternatives now, though.

Good luck!

Thanks for the kind words: there are a bunch of older discussions here: https://github.com/photostructure/exiftool-vendored.js/issues?q=is%3Aissue+lambda

(but I think you're going to be fighting lambda's external-process-killing service, hence my guidance above)
