Missing utility class in bootstrap 5

[NotMyFault]

Hey,

I'm updating to bootstrap 5 at the moment, but less-loader, one of the components of webpack, complains about missing api classes of bootstrap when I'm building the project:

[INFO] ERROR in ./src/main/less/pluginSetupWizard.less (./src/main/less/pluginSetupWizard.less.webpack[javascript/auto]!=!./node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[0].use[2]!./node_modules/postcss-loader/dist/cjs.js??ruleSet[1].rules[0].use[3]!./node_modules/less-loader/dist/cjs.js??ruleSet[1].rules[0].use[4]!./src/main/less/pluginSetupWizard.less)

The bootstrap upgrade docs don't mention anything in terms of webpack or its components, which would require special treatment, am I missing something?

Thanks in advance!
