@ChristophWurst I reviewed the failure. This PR should not be merged as-is.

Root cause

node-polyfill-webpack-plugin@3.0.0 configured its buffer fallback with:

require.resolve('buffer/')

That resolves to the fully specified buffer/index.js entry point, which works for both CommonJS and strict ESM importers.

In node-polyfill-webpack-plugin@4.1.0, the plugin now obtains the alias from node-stdlib-browser:

buffer: stdLibBrowser.buffer

In this install, that becomes the absolute directory:

.../node_modules/node-stdlib-browser/node_modules/buffer

rather than .../buffer/index.js.

Webpack is trying to bundle strict ESM dependencies. Strict ESM requires fully specified paths, so it refuses to infer index.js for that absolute directory alias. The package is present in the lockfile; this is not a failed or incomplete npm ci installation.

Why html-to-text appears in the error

html-to-text’s nested entities@7 is one consumer that imports buffer, but it is not the underlying issue. The same alias fails for multiple ESM dependencies:

• @nextcloud/files
• axios
• es-toolkit
• entities via html-to-text
• js-base64

That is why both the release-package build and front-end E2E setup fail during webpack compilation.

Recommended resolution

Keep node-polyfill-webpack-plugin on v3 until the v4 package provides a fully specified buffer fallback, or until this project explicitly overrides both the buffer fallback and Buffer provider with a resolved buffer/index.js entry point. The latter requires configuration work and an explicit direct buffer dependency, so it is outside the scope of this Renovate-only bump.

The front-end unit job passing does not invalidate this: it runs Vitest and does not execute the production webpack build that encounters strict ESM modules.
