I am having the same issue, have you been able to fix it?

[octet-stream]

Hi. Sorry for the late response. How can I reproduce the issue?

[FrankyFrankFrank]

@cfficaurzua What version of Typescript are you using? This package uses 4.8.4. When we updated from 3.* we were able to get over the issue.

Note made in #12

What version of Typescript are you using?

The original post mentions version 4.7.4.
I already decided to remove this helper and write necessary types myself instead. This change will be released soon.

I've also tested tsc compilation in v4.3.x:

npm exec --package=typescript@4.3 -- tsc --noEmit

so that would likely be the minimum required version, because it was the one introducing support for private methods from the ECMAScript spec.

Try https://github.com/octet-stream/form-data-encoder/releases/tag/v2.1.3. I hope the issue is resolved.

I am closing this as completed. Feel free to reopen if the issue is still remains in the latest version.
