Running build causes error

[doublejosh]

When trying to build via npm run build, the /dist folder is created, but you get the following error...

[!] Error: Invalid format: esm - valid options are amd, cjs, es, iife, umd

I tried to solve this by installing esm via npm i esm, but it still results in the same error.

Looks like a problem with the version of rollup you are using. Can you specify the version of rollup being used?

[joelewis]

As a workaround, you can change the entry in rollup.config.js from "esm" to "es". This should fix the problem.

It should have been using the local copy of rollup declared in prosemirror-mentions/package.json which is 0.50.1.

I was able to use the workaround, but it seems like the main build will produce an error.
