rollup-plugin-workbox 5.2.0 error: [!] SyntaxError: Cannot use import statement outside a module

My builds failed on this newest version of the plugin. The full error was:

[!] SyntaxError: Cannot use import statement outside a module
C:\D2L\personal\brightspaceui-core-bundler\node_modules\rollup-plugin-workbox\dist\index.js:1
import { generateSW as _generateSw, injectManifest as _injectManifest, } from 'workbox-build';

Reverting to version 5.1.0 solved the issue. Do I need to change something to work with the newest version of the plugin?
