I am getting this webpack error when running yarn deploy for my github page.

I am using gatsby-plugin-styled-components: "2.0.2"and styled-components: "2.2.4".

gatsby-pluging-styled-components should have handled the SSR right? or do i still have to configure it manually? it worked fine a few months ago when i deployed the first version of my github page.

Issue can be closed. Realized its because i did not install the peer dependency for styled-components.

@jaanhio Can you explain how did you solved this? I am also getting same kind of error.

TypeError: _material_ui_core_styles__WEBPACK_IMPORTED_MODULE_10__.ServerStyleSheets is not a constructor

For anyone coming here from google....
make sure @material-ui/core/styles actually exports ServerStyleSheets

this lead me to realize I'm running an older material-ui/core (3.9.x)
fixed by upgrading to 4.5.1
