Action does not publish non-scoped package to NPM

[WillsterJohnson]

EDIT: for now I'm going to continue working on the project, the repo at the time of writing is at this commit

Context

NPM package | GitHub repo | workflow file

The NPM_AUTH_TOKEN repo secret is a "publish" token, and I have temporarily disabled 2FA to try to get this working. (this same error also appears when using an "automation" token, and as expected a "read only" token will also refuse to publish).

You might notice the actions tab has a dozen workflow runs; this problem has persisted for the last 12 hours and recently switching to this action from npm publish has done absolutely nothing to change it.

The part that matters

My package just-checkit is currently on npm at version 0.1.0, published from my local machine.

When trying to publish 0.1.2, which is not (and never has been) on npm. via a github workflow I get the error output below.

I'm convinced this is an authorisation error, as making a PUT request to my package on the registry with valid authentication and without any request body doesn't reject with 404 NOT FOUND;
i.e. if this request was authorised it would have a different error message.

Output;

// tarball info, everything exactly as it should be

Like I said this has been the exact same error for a while, and the sum of all the google searches I've made is roughly "lol good luck".

Did I Google it?

Yes, many, many times.

It seems that no one has had this issue before, or at least the cause of it for them is different from the cause here, none of the recommended solutions work.

I've been dragged all across github issues, stack overflow, npm docs, github community, and I'm honestly quite concerned that nothing I've found has worked.

The only time the error message changed was when I introduced a new error before this one by implementing a "solution".

Hey @WillsterJohnson, the links you posted are all dead, so I'm going to close this issue as "can't reproduce." Please let me know if you're still experiencing issues and we can re-open the ticket if we've got more recent, concrete reproduction steps

[WillsterJohnson]

Yeah, I kinda abandoned the project I was using this with a while back and it must've got caught up in my annual clean up.
I don't remember enough about this issue to reproduce it, so long as no one else is experiencing this problem it's all good from me.
