Future<List<WooProductCategory>> getProductCategories

[CodesbyRobot]

Exception has occurred.
_Exception (Exception: WooCommerce Error!
code: rest_invalid_param

calling woocommerce.getProductCategories(orderby: "") throws the exception above with the message:
Orderby isn't a valid parameter.

The Problem is

woocommerce.getProductCategories(orderby: "")

you are passing an empty value there.

orderby - string
Sort collection by resource attribute.
Options: 
id, include, name, slug, term_group, description and count. Default is name.

It is just to show which part was giving errors, i put the values inside but the error isn't about them.

I tested all the options for orderBy by itself alone and along with order (asc | desc)

await wooCommerce.getProductCategories(order: 'asc', orderBy: "id");

the only time it had thrown this woocommerce error below as the one u also have shown

Exception has occurred.
_Exception (Exception: WooCommerce Error!
code: rest_invalid_param
message: Invalid parameter(s): orderby
status: 400)

is when the orderBy value is any other than the provided options in the Woocommerce Rest Api.
(id, include, name, slug, term_group, description , count).

So if the error is not otherwise, please do provide some more details.
maybe in another parameter like include or exclude??

exclude	array	Ensure result set excludes specific ids.
include	array	Limit result set to specific ids.
