Error with latest terser plugin

[aesislabs]

With the latest terser-webpack-plugin I get an error, rolling back to a 4.x version fixes the problem:

10% [frontend] building[webpack-cli] Invalid options object. Terser Plugin has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'minimizer'. These properties are valid:
   object { test?, include?, exclude?, terserOptions?, extractComments?, parallel?, minify? }
