@bigcommerce/catalyst-core	patch

Check for error.type instead of error.name auth error in Login, since error.name gets minified in production and the check never returns true. Additionally, add a check for the cause.err to be of type BigcommerceGQLError.

Migration:

• Change error.name === 'CallbackRouteError' to error.type === 'CallbackRouteError' check in the error handling of the login action and include error.cause.err instanceof BigCommerceGQLError.
