I ran into this same error when using this library in an AWS lambda function with a NodeJS environment.

Same error in pure project with node-pptx only. On Windows 10.

Hi guys. Same error too and I resolved.

/node_modules/nodejs-pptx/lib/factories/index.js:42

- if (zip.files.hasOwnProperty(key)) {
+ if (Object.prototype.hasOwnProperty.call(zip.files, key)) {

like https://github.com/heavysixer/node-pptx/pull/84/commits/efe21998639f2b5295f4350e860cfe0a2238a2d7

have a good day. :)
