Set posthtml expression options

[Damir]

When I try to add posthtml expression options then it fail:

options: {
              plugins: [
                require("posthtml-expressions")({
                  removeScriptLocals: true 
                }),
                require("posthtml-extend")({
                  encoding: "utf8",
                  root: "./src/"
                }),
              ],
            },

Error:
