Compatibility issue with sass-loader, Error: Sass Loader has been initialised using an options object that does not match the API schema. - options has an unknown property 'importer'.

[sainisagar310]

The version 1.0.8 (latest) of antd-scss-theme-plugin is not compatible with sass-loader(8.0.0) latest. It shows the following error:

Invalid options object. Sass Loader has been initialised using an options object that does not match the API schema. options has an unknown property 'importer'. These properties are valid: object { implementation?, sassOptions?, prependData?, sourceMap?, webpackImporter? }

@sainisagar310 Waiting for the same isue.

Looks like the lib is valid, waiting for importer - which makes the ERROR issue to be suspicious.

Using Webpack 3, and verified the package libraries are ok.

I managed to work around this for the time being by downgrading sass-loader to 7.3.1.

@cdwieber is the issue related to sass-loader v8 and above? how did u end up with 7.3.1?

As Chris suggested - 7.3.1 resolved it for me as well. בתאריך יום ד׳, 29 בינו' 2020, 2:26, מאת Altug Sahin ‏< notifications@github.com>:
