Build failure on gatsby App because of object.assign not resolve in node_modules/assert

Working on Gatsby app and suddenly getting this issue, causing build fail:

Generating development JavaScript bundle failed

Can't resolve 'object.assign/polyfill' in 'C:\Home\ARK\Repos\shape-website-3\shape-website\website\node_modules\assert'

If you're trying to use a package make sure that 'object.assign/polyfill' is installed. If you're trying to use a local file make sure that the path is correct.

File: node_modules\assert\assert.js

Required urgent attention, please!

Reproduce el fallo del development-bundle de Gatsby e inspecciona node_modules/assert/assert.js, centrándote en su referencia a object.assign/polyfill. Confirma el comportamiento de la resolución de dependencias en una compilación de Gatsby; se considera terminado cuando el bundle se completa sin el error de módulo faltante indicado.
